Fitbit Surge review

UPDATED: Does Fitbit's fitness super watch live up to its billing?

The Fitbit Surge is the company's first true sports tracking wearable aimed at those who love running, cycling and working out.

Fitbit has described the Surge as its “most advanced tracker to date", and with optical heart rate sensing and GPS built-in, it's more than a match for sports watches from likes of Garmin and Polar.

King pair: Fitbit Charge review & Fitbit Charge HR review

After strapping it on for the original review we've gone back and revisited it with the addition of Fitbit's new cycling mode.

Read on for our full Fitbit Surge review.

Fitbit Surge: Design, build quality, display

Unlike the Fitbit Zip and the Fitbit Flex that came before it, the Surge shuns the traditional activity tracker band form factor and it's definitely more smartwatch than fitness tracker.

However, while the Android Wear brigade are hardly fashionista head-turners (the LG G Watch R and the Asus ZenWatch are semi-stylish rather than stunning) they do somewhat put the Surge to shame when it comes to aesthetics.

Fitbit Surge review

The Fitbit Surge's rubber strap, which comes in black, blue or tangerine looks nice enough and, crucially, is both comfy and secure, but it's hard to look past that dated looking display and the increase in girth from the modules bottom to top end is rather bizarre.

Wareable guide: Best fitness trackers you can buy

The display is a rather drab looking touchscreen monochrome 1.25-inch LCD number that uses a plethora of greyish blue variants for its different homescreens and menus. There's a solitary button on the left side for switching between the live view mode of your daily stats and the function screens (this also switches from a light on dark to dark on light colour setup) and the two buttons on the right are used as selection inputs.

This physical and capacitive control arrangement works well however; it's easy to navigate around the Surge's options and features without getting lost, and we've had absolutely no issues with touchscreen responsiveness, even in the pouring rain.

The LCD screen has a backlight so it's also usable in low light situations ‚Äď you can toggle this light on or off, or set it to automatically come on when in use ‚Äď through the settings menu on the device itself rather than having to use the app.

Stupidly, if you want to change the watch face ‚Äď there's four to choose from ‚Äď you do have to use the app, the settings on the device only extend to the backlight, switching notifications on or off, toggling Bluetooth, setting the heart rate monitoring power options and turning the Surge off.

Fitbit Surge: Activity and sleep tracking

Fitbit Surge review

Fitbit's raison d'etre, up until this point at least, was everyday fitness tracking ‚Äď so let's kick off with that aspect of the Surge's armoury.

The Fitbit Surge is capable of tracking steps, distance travelled, calories burned, floors climbed, elevation and active minutes thanks to its 3-axis accelerometer, a 3-axis gyroscope and digital compass.

These stats are not only synced to the Fitbit app (which we'll come to in more detail later) but are also displayed on the device's display. From the regular clock face you simply swipe left and you'll see all your daily totals on display. It's incredibly easy to use and much less fiddly than opening up an app to see how you're doing, as would be the case with older Fitbit devices, as well as incoming rivals like the Jawbone UP3.

Must read: The real world wrist-based heart rate monitoring test

The activity tracking is, as you'd expect from a company with plenty of experience in this area, incredibly reliable (we tested against older Fitbit models, as well as rival activity bands) and the Surge does a great job of motivating thanks to the ease of seeing how well you are performing against your goals.

There's also sleep tracking with the Surge and, like the new Fitbit Charge models, your zzzzs will be monitored automatically (unlike the older Flex which required a manual, push of a button sleep command) and there's a vibration-based silent alarm on offer too.

The Surge records days of detailed motion data, minute by minute, and keeps tabs on your daily totals for a month. It can also store heart rate data at 1-second intervals during exercise tracking and at 5-second intervals all other times.

Fitbit Surge: Heart rate monitoring

Fitbit Surge review

24/7 heart rate monitoring, using Fitbit's new PurePulse technology (that is also found in the Fitbit Charge HR), is a major feature of the Surge and puts the device squarely up against the likes of the Basis Peak and the Microsoft Band.

It means that, not only can you use the built in optical heart rate sensor to guide you during runs and workouts, and allow you to do detailed bpm training, you can also monitor your resting heart rate everyday, allowing you to monitor it over time and see what events and activities in your life cause it to fluctuate.

Fitbit's PurePulse tech uses LED lights (you'll see them on the back flashing green as you remove the Surge) to detect your blood volume changes as your heart beats and, combined with the company's algorithms, you'll be able to get a more accurate calorie burn figure and keep a closer eye on your health.

You will of course, as already mentioned, also be able to train within heart rate zones and maximise cardio workouts. We tested the Surge's bpm skills against a couple of other optical heart rate sensors (including the new Mio Fuse band) and found the results to be pretty consistent.

So while an optical, wrist-based, heart rate monitoring isn't likely to be as accurate as a dedicated chest-strap, we'd say the Surge is as reliable as any of its main rivals for a general gauge of bpm performance.

Fitbit Surge: GPS running and workouts

The next big function that helps the Surge stand out from the crowd is the inclusion of GPS connectivity. This means that you can now track runs using a Fitbit wearable without the need to take your smartphone out and about with you as well. Essentially, it puts the Surge head-to-head with dedicated GPS running watches but its main rival is probably the activity tracking hybrid Polar M400 that also has GPS smarts.

It's easy to start a run with the Surge, simply navigate to the main running homescreen and select the type of run you want: free, lap or treadmill. The first one is the one you'll use most, the second allows you to press a button to record lap times and the third is a non-GPS option that uses the step algorithm to track your gym jogs ‚Äď it's best to calibrate your stride length within the Fitbit app if you're going to be doing a lot of these.

For the GPS running the satellite lock is pretty quick ‚Äď faster than an Adidas miCoach Smart Run, not as fast as a Polar M400 ‚Äď and once you're off you're presented with the running display, which shows distance, time and pace. Swiping to the left swaps pace for steps, calories or heartbeat but there's no way of changing the other two metrics, or the order things are shown.

Now, while GPS tracking is the only real way of accurately tracking a run, there's always some discrepancies between devices ‚Äď even ones made by the same manufacturer ‚Äď due to the satellite being used, the strength of the signal, interference and so on. However, these discrepancies are usually around 2-3% at most. We twice tested the Surge against the Adidas miCoach, and once against both the Sony SmartWatch 3 and Polar M400 and found that, over 5km, the Surge claimed we ran 420m less than the miCoach and, over 10km, 700m less than both the Polar and Sony recorded. That's 7-9% different. Not ideal, especially given that we tested it against devices giving consistent results, and ones that we had proved reliable in the past when compared to rivals themselves.

You can set up the Fitbit to record other sports ‚Äď weights, golf, circuit training, yoga, golf, tennis, hiking and a load more ‚Äď and you can also choose which ones of these sports you want to include within the Exercise area of the device itself.

These sessions are then automatically synced within your log on the Fitbit app, with heart rate data and, if applicable, GPS data on offer. However, these sessions are essentially just labels for the app. The golf function, for example, has no course data and won't record your shots ‚Äď it will simply map your route using GPS, calculate the distance you walked and keep tabs on your bpm.

Fitbit Surge: New Bike mode

An ominous omission from the Fitbit Surge at launch was a dedicated cycling tracking feature, which was a big drawback for bike lovers. However, Fitbit has added a new Bike Mode to its exercise line up.

The mode brings the same level of detail as Surge provides for running, with time, pace and heart rate zones provided. The app provides graphs and charts of your session, as well as a map of your route.

However, the mode isn't as detailed as we've seen with body mounted wearables, such as the Wahoo Tickr X, which can record cadence, which is an important stat for cyclists.

It makes the Surge a useful watch for cyclists, but like much of its reporting, it doesn't quite match the immense detail of specialists sports tracking wearables from the likes of Garmin.

Fitbit Surge: The Fitbit app

Fitbit Surge review

The Fitbit Surge syncs to your smartphone app using Bluetooth, or your PC or Mac using a wireless dongle if you don't have access to an Android, Windows Phone or iOS device. Once synced with the mobile app, data is stored in the cloud and will appear on the slightly more in-depth desktop version too. Your data will also sync with the info from your Fitbit Aria Wi-Fi Scale, and brings in your data from your old Fitbit devices as well.

When syncing your Surge to the Fitbit app ‚Äď the same app you'd have been using already for your old Fitbit device ‚Äď you'll be asked if you want your new super watch to replace the existing stored wearable. The Fitbit app can't handle more than one tracker at a time and you'll have to delete your existing Flex, for example, before you can pair your Surge.

During our Fitbit Charge review we mentioned this is a bit silly as wearables should be chop-and-changeable: surely Fitbit would benefit by letting users don multiple devices? This setup discourages users from getting both a Charge and Surge.

The Fitbit Surge section of the app lets you see your step count, your current heart rate, the distance you've covered, calories burned, floors climbed, active minutes and also lists all your workouts. From within each of these you can select to see more info and be presented with a plethora of graphs and historical date (daily, weekly, monthly). The app also allows you to record extra workouts, share and compete with your friends, log your food intake and earn badges based on your activity achievements and you can also use the app to change some of the settings for the Surge.

Fitbit Surge: Smartwatch notifications

Fitbit Surge review

The Fitbit Surge is not a smartwatch. In terms of smartphones notifications you're looking at incoming call alerts, missed calls and text messages. And that's it. You can forget about WhatsApp, Facebook, Twitter and the like ‚Äď the Surge doesn't even offer native app updates like emails and calendar reminders. A crying shame and certainly not what you'd expect from a 'super watch'.

We hope Fitbit adds extra notifications soon, the likes of the Garmin Vivosmart and the Sony SmartBand Talk offer third-party app support and even the Acer Liquid Leap has calendar reminders.

Smartphone music control is on offer, but only during workouts. The display shows track info and you can skip, play and pause using the physical buttons.

Fitbit Surge: Battery life and extras

Fitbit seems confused about two things when it comes to the Surge: Battery life and water resistance. On the Surge's official webpage it states that the battery life is both ‚Äúup to 5 days" and ‚Äú7+ days". You don't need to be a genius to work out that doesn't make sense. We got just over three full days out of it, but that did include an hour or so a day of GPS based activity. It charges from a proprietary connector attached to a USB cable ‚Äď annoyingly not the same connector as the Fitbit Charge, though.

The Surge carries a water resistant rating of 5ATM, which should mean you'd have no problems wearing it in the pool - although Fitbit advises against it. That doesn't really make sense as a 5ATM rating means it should withstand the pressure of 50m of water.

Fitbit Surge
By Fitbit
When the Surge was first announced at the end of last year, we were massively excited, and the company‚Äôs claims that it was a ‚Äúfitness super watch‚ÄĚ seemed reasonable. A few months on though and the Garmin Vivoactive has been announced, with its endless array of sporty features, and the Surge now really only has the 24/7 heart rate monitoring as its USP. The design is dated at best, ugly at worst, the smartwatch functions are incredibly basic, and we‚Äôre not convinced one of its key components ‚Äď GPS tracking ‚Äď is entirely accurate. However, as an everyday activity tracker, it‚Äôs great, and for casual runners getting into heart-rate training it might just be the answer. However, at ¬£199 / $249, it may be too pricey a stepping stone for some.

  • Activity tracking is great
  • Very easy to use
  • 24/7 heart rate monitoring
  • Automatic sleep tracking
  • Smartphone notifications basic
  • GPS accuracy debatable
  • Uninspiring design and display
  • It‚Äôs not cheap

    I bought it and returned it pretty quickly for most of the reasons stated in the review.  I thought the looks were fine, and the band was extremely comfortable, but the GPS tracking was awful.  I went for a 30 mile bike ride, and it told me it was 20.  That was a huge difference.

    HR monitoring was so-so.  It was interesting to see my heart rate log while sleeping at night.     

    I was looking for more of a athletic sports watch.  Counting steps and floors is irrelevant to me because those are just normal day to day activities.  I race bicycles, and this device just can't monitor the HR or distance correctly.

    Sleep monitoring was not so good either. It told me I had a sleep efficient of 97% despite the fact that I woke up 11x (which I don't remember).  I'm thinking if I wake up 11x, my efficiency should be much lower.  Also, it would give me multiple and different reports for an evening.  For each night, there would be a report for 2-3 hours, another for an hour or two, and then another.  I have a Zeo, and find that to be consistent.  The scores it gives me pretty well correspond to how I feel. 

    The Alerts (email and texts) don't work if you have a Windows phone.  I did not see that in any previous reviews.   

    Even though it's not the device for me, I did think it was pretty spiffy.  The website and set up was useful.  And in my opinion, it would be very beneficial for someone who is not so athletic, but wants to increase and monitor their activity.  Just paying attention to the various things that the site monitors is helpful. 

    I'd give it 3.5 stars out of 5.

    Thanks for the review. Got a question though.

    Is it possible to export GPS tracked runs, so I can import my activities to third-party sites (e.g. Runtastic or Sportics)?

    Garmin offers such a functionality by providing tcx-files through Garmin Connect.

    Thank you in advance,


    • p.lamkin·

      Afraid not.

      • Raddy·

        Thank you again!

  • kari·

    Does it have a interval timer option?

  • Gabdoyle·

    ive had my fitbit for 10 days and Im truly disappointed with the GPS function. My 9 km bike ride to work has been logged as a 1.6 km, 2.35km, anf 5km, distance.

    So it the GPS is useless except for running really. Even for hiking its limited sice you cant see coordinates which is useful in the mountains.

  • maprouty·

    The screen is very dark, much darker than the other models.  Can you brighten the screen?  I just bought the unit last night and will return if I can't get a brighter screen like the other models.  

  • tinypond·

    I bought one and will be returning it shortly. 


    Battery Life 4 days. Software is really easy and good..


    Band did not fit correctly really wide design and thin rubber, Thick Triangle head of watch  and sits up like a high rise on wrist.

    Suggestion  to FitBit Surge designers.

    Make band replaceable and have other cool colors other than  black.

    Screen has bulky black frame around it, take images to the edges and make ergonomically better style.

    Seems to be some inconsistencies with these statements.  Enthused by the reference to the Garmin Vivoactive, I went exploring.  For the same price as the Fitbit Surge, one must buy an optional heart rate monitor for $69.  Additionally, since GPS is built into the Surge, it would seem one might be able to ascertain forward speed, albeit approximate, but the Vivoactive offers yet another optional accessory package for $69, to include bike speed and cadence.

    Please understand I endorse neither the Fitbit nor the Vivoactive.  I am simply looking for the best device to track heart rate and distance on my bicycle.

    I've had mine since January and have used it daily.  I first had to get used to the very dim LED lighting on the face.  It's very hard to see in the daytime unless the sun hits it just right.  It's also bulky and I have to be careful not to bang it when walking through a doorway.  The text and call notifications don't work.  I have the Samsung Galaxy S4.  I did get some but never 100%.  Their support folks are useless.  The discussion pages at Fitbit are loaded with similar complaints about notifications not working.  They recently upgraded the firmware and now the face defaults to a clock screen after about 10 seconds.  I bought a fitness tracker, not a watch.  I used the GPS feature once and it took several minutes to find me.  I wish that I would have looked at other options before committing to the Surge.

  • Abey·

    Before you purchase fitbit products please check if you can download the software to your desired device (Tab/ Phone). I bought a Fitbit Surge and they don‚Äôt allow me to download the software in my country. you have to be using a US app store account. the tech support of fit bit says ‚Äútough luck‚ÄĚ. please do not waste money. check app first as without the app nothing much you can do with the USD 250 worth band.

  • mkelly·

    Would you recommend getting this for a runner? I am looking for a band that will track my distance efficiently and accurately. Is this band trustworthy or not?

    • Chip·

      Go with a garmin forerunner, its cheaper and better built for running

  • RoadKill·

    As an avid athlete and purchaser of the FitBit Surge, I can tell you that this device falls very short of all of its claims. It doesn't sync reliably, it doesn't charge reliably (eventually the plug becomes too loose), and the features offered on the website for syncing with other activity tracking sites like Strava, MyFitnessPal and Endomondo are frequently not working. The technical support does not seem able to understand or take appropriate actions to remedy these short comings. If FitBit wants to compete with other companies offering similar products, they are going to need to do some significant work.

  • juliads·

    It says it has smart phone music. My question is do I need an I phone or is any smart phone alright. I'm more concerned with seeing my calls and text while working out and not needing to keep my android on me.

  • jmetcalf0926·

     The reviewer seems to be confused on one fact: music control is available on the Surge, even when not in workout mode.  There is an option for "Bluetooth classic" that allows you to connect to your paired device's music player and control it by double-tapping the left button. 

    Bought mine as a generic fitness tracker / watch at launch and I can honestly say that I haven't had an issue with it.  I'm actually kind of glad that my wrist isn't vibrating all day long with third-party notifications. 


    How do you get replacement bands?? Mine is broke & if cant replace going back to flex

    • Passionfruit56·

      How do you get a replacement band mines is broken, therefore , I can't use my fitbit!

  • galtobelli·

    Yes you can: just log in into your Runtastic account directly on Runtastic website, then connect your fitbit account into the settings panel to it and everything will be automatically synced.

  • TWGator·

    You state that the band comes in black, blue, and tangerine. However, even though the blue and tangerine colors have been listed and even pictured on the Fitbit website since day one, frustratingly these colors are still not available. Were you able to actually get a watch in these colors? According to Fitbit support I can't order in any other color than black because they simply don't exist. Yet. Told "very soon", but heard that for months now. Thanks!

  • UnhappyUser·

    People are obviously easier to please than I am.  reviewing all the information located throughout the web on Fitbit Surge, everyone is rating it 3 stars or better out of 5.  Me, I am not so happy.

    While it tracks my walking distances correctly, the good things end there.  +4 Stars

    The backlighting on the screen is impossible to read when I walk early in the morning and I either have to carry a light or wait until I come to a streetlight.  UNSAT - 5 stars.

    Next, while I climb ZERO staircases, and supposedly the Surge bases floors climbed by atmospheric pressure changes, sitting at my desk, doing regular menial tasks of entering data, the Surge credits me with up to 82 floors in a single day and averages about 34+ per day.  For example, just in typing this comment, the Surge is reporting that I have climbed 16 floors.  NOT EVEN CLOSE to accurate.  -5 Stars

    My Fitbit One reports that I have HALF the steps that my Fitbit Surge reports, but Fitbit says that the accuracy should be between a few percentage points of each other...well, I guess HALF is a "few percentage points" and so I guess I can't ding them for that....WRONG.  - 5 Stars.

    All in all, not happy with the Fitbit Surge, the cost of the unit, the battery life (less than 2 days), or the INACCURACY of the product.  I'd sell it, but how do you sell something that is utterly worthless unless you LIE about how good it is?

  • klkpl·

    Just bought surge and love it, I read this review prior to buying and had few doubts but ultimately decided to go for it and I don't regret. 

    Design ? not sure what is your issue here the watch looks great for me and is very comfy, discrete style that goes well with casual and business clothes too, size is also perfect for me (got large) 

    God tracking? it's completely opposite to what you said in review - it's super accurate, I compared drawing on the map in Fitbit with the route in my head as I know it very well and it was spot on, but I only tried it in the urban area if that makes any difference maybe 

    Display is OK not great, but no drama either, could be little brighter (unless it's somewhere in setting I didn't figure out yet) 

    Heart rate, steps, sleep pattern that seem to be captured very good and accurate too, used to have another much cheaper fit watch and results were all over the shop, surge even if of course there is some inaccuracy is consistent - which leads me to believe numbers showed are not random like on some cheap fit bands.

    Yeah it's bit pricey but in fairness I'm delighted with this purchase. 3 star is not harming review in my eyes it deserves at least 4 stars, for me 4,5 / 5.


  • DHK1932·

    All these negative reports have me a little  worried now, as I just ordered my Surge yesterday, however I am somewhat optimistic after reading  last review dated aug. 25th. I will submit my review at a later date after I have had a chance to evaluate it myself.

  • Tamas·

    it works just perfectly for me.I used it today from the first time,and I am very happy,the gps is spot on!

  • Winniewoo02·

    Winniewoo#02, Hi I got my surge from my daughter as a present and it worked fine for the first few days and even charged fine but now I plugged it in and it won't charge . Can anybody help? 

    • TomasH·

      Dear Winniewoo#02, as written above the connection of the charging cable to the watch isn't too tight (i.e. mechanically not stable). So make sure that the cable doesn't get loose when you lay down the watch for giving it a rest while charging. If it still doesn't work you might have to check with your store and ask for a replacement.

      Apart from that I cannot support those statements above on poor GPS tracking results. My watch found a distance of 9.83 km for my 10km-run at the EVL event in June. It records my two most often run tracks with standard deviations of 1.2% and 1.4% respectively. So both accuracy (compared to a known distance) and consistency don't seem to be too bad (at least for "running").                                

      I'm glad that yesterday's software update added a stopwatch and a timer count down functionality.

  • URGreat·

    First, for 275$CAN, they should think about competition and it is all about looks. That screen is so low quality I won't even botter spending that amount of money on that fit watch.

  • JimmyB·

    5 ATM is 40m, not 50m. You forgot you start with one on the surface.

  • stjago72·

    My sleep is not recorded correctly. The problem started last Friday, Oct 16. No information logged for Friday, Oct 16, Friday's information was finally logged but recorded into Saturday and since then every night's sleep data is recorded in the next day. Has anyone else seen this issue? Fitbit does not seem to know how to correct this and for some techs they are making it out to be my misunderstanding of now the Fitbit Surge works. My question is why did it track accurately from August 29 (date of purchase) until October 15 and now this seems to be in my head. Help!!!!!

  • mastersurfer·

    Well I really like the device, the Fitbit Surge, but the band isn't going to make it more than 6 months. That's a lot of money to shell out for a device that is essentially disposable if you can't get replacement bands! Serious design flaw really.

  • Smanth·

    I love my fitbit, but unfortunately today have taken a tumble off my bike and smashed the screen. Is it possible to fix the screen? It all still works other than that!!! Gutted is an understatement as it was a birthday present :( 

  • Oneozzie·

    I bought a used Fitbit Surge & shortly after the band snapped - Fitbit didn't want to know me !

    If you can't replace the band this product has a very limited life - bloody awful considering the purchase price - talk about "built in obsolescence!"

  • muddmann·

    after 2 months my band broke  , can it be replaced i enjoy the watch an the features,, i am willing to purchase a band if possible , i just can not find online Tony

  • geminiabode·

    I have been a avid fitbit user since past 3 to 4 years. However based on a recent issue and my research thereafter, I have concluded that fitbit has a serious security issues with the IT system and managing customer data. One fine day, fitbit tells me that my account does not exist and never existed. That is really scary. There goes years worth of fitness data in the drain. Further more they locate someone else's email login on my tracker. There security department has no clue and never contacted me. From the forums I found it a common problem. They try to sell it to the customers as a security breach (which given their weak security is a major vulnerability) but they hide the underlying issue of their IT systems which causes database glitches and evidently has no trace of audit or security to find out whats happening with a customer account and his data. This attitude of carelessness towards protecting customer data will definitely wean away customers from fitbit.

  • Hauskie·

    I just received a Surge for Christmas.  I set it up last night.  I woke up this morning and did a synch.  It did not show any sleep last night.  It did show sleep on the 19th of December instead of the 25th.  Very interesting.  Perhaps something is off that I don't know about.  At any rate, the GPS is pretty accurate.  I went for a short walk (late at night) and it registered the walk accurately and showed it on the map.  It is interesting but I am not sure how well it will work.  I have had a charge for about a year.  It has been quite inaccurate.  I was hoping that the Surge would be more accurate.   I also would like to be able to track my bike rides accurately.  I will need more time to evaluate it.  So far, good for tracking, not good for sleep.  (That may be something I can fix don't know yet)  I will be giving it a good test over the next couple of weeks.

    Can you change the face settings to show your heart rate instead of the time?

    Or add the heart rate to the main screen?

  • tnewc·

    So, can the band be replaced?

  • Jenks·

    I purchased  a Fitbit Surge within 3 weeks I had to charge it every 20 hours, and even then I had it set on its minimal activities settings, ABSOLUTE  WAIST of  MONEY.

  • Jono·

    Not at all happy with the Surge.

    Purchased it a few months ago. Never lasted five days battery even without any extra functions running. Three months on I can't swipe across and view the other screens on the watch and the battery only last 24-36 hours when fully charged. Useless as a anything other than a watch that you have to charge every night.

    The app was fairly good. The GPS was usually out by around 25% when walking. Usually less than 15% when running. 

  • Hippycyclista·

    Fitbit is dead to me. I've owned 3. The original gave me a rash and it didn't latch securely. It fell of at the gym and was never found again.  My husband bought the Surge for me on my birthday in 2015 but I quickly found out that you couldn't hike, bike or run without activating the GPS.  When the GPS was active it sucked down the battery before I had completed my activity.  As a result I only used the fitness tracker for gym or indoor workouts and spinning. I live in the Houston area where it's humid, and I sweat a lot giving me problems with the touchscreen.  It goes inoperable when I need it most.  The bands peel on the surface and rip on the underside near the screws.  They also only have small and large sizes when most of the population is probably a medium???? I'm switching to GARMIN VIVOACTIVE HR ASAP!

  • dickie·

    I have had the Surge for six months and have yet to receive a single text message.  Overseas email support is useless and have me going around in circles since I got it.  Do not waste your money!

    Have had a very disappointing experience with this watch over the last 1 year of ownership.  (purchased in India through Amazon). the GPS accuracy at best is dismal. have after multiple fights received two replacements for the device, with all three devices sharing the same dismal gps accuracy. major concern is that gps is way off considering garmin and tomtom (i owned one before fitbit and i can still vouch for tom tom's accurary even on rainy and cloudy days). heart rate accuracy is decent. 

    However, due to the gps inaccuracies i have nothing but a thumbs down to this device.  as of now i am holding on to it, as i cannot afford to spend another 300-400 usd for a new fitness watch. 

    My verdict: Big claims, poor delivery on gps front.

    i had bought the fit bit in India through Amazon. Had a tom tom (without heart rate) prior to this, but bought the surge, due to its tall claims on gps and lifestyle functions. I am extremely disappointed on the gps with this device being inaccurate (thats the most decent word that i can use).  Never shows distance inaccurate. Map data shows i running through walls, sea, hills, forest and what not. i can vouch for the accuracy of the tom tom despite whatever being the weather. 

    After complaining a lot, i have already received two replacements (currently using the third ) with all three miserably failing in the gps department.  this watch is basically a rip off and not for serious running.  as of now i am using it as i do not want to spend any more money on fitness watches. 

    Extremely disappointed . My Verdict: Tall claims, little delivery. Better to avoid this product.

    I have now owned two of them.  On the first one the band separated on the backside by the screws and the screen cracked across the top overnight.  They replaced it rather quickly.  The second one lasted quite a bit longer but now suffers the same band separation in the exact same spot.  Only difference is this time they only offer a 25% discount on a new one since it is longer than a year since original purchase.  In my experience this watch was made to last about a year so keep that in mind if you are looking at a gps watch.

    I've had two that have done exactly the same thing. Extremely poor build quality!
