Those UP3 delays were a pain in Jawbone's ass but they sure did help Fitbit. New figures from analyst firm Canalys show that 7 million fitness bands - excluding clip-on trackers - were sold in Q1 of 2015 and that Fitbit came out on top.
Canalys estimates that fitness tracker sales have increased 150% year-on-year but we don't have estimates of exactly how many Surge, Charge HR, Charge and Flex trackers Fitbit has sold in 2015 so far.
We imagine a big chunk of those will be the Charge HR which has long sat atop our best fitness trackers list. How happy many of the people who have bought one remains to be seen, judging by the number of comments on Fitbit rashes on Wareable, though.
We also know that the budget Mi Band, which is now on sale for $20 in the US and Europe, secured Xiaomi second place in sales.
And, it's not stated directly, but it seems like Garmin takes third place - the report says Garmin had a strong quarter to kick off 2015 with its new devices including the excellent Vivoactive smartwatch and Vivofit 2 fitness band.

Another report published this week by Argus Insights claims that Fitbit has a massive 68% share of the fitness tracker market which has grown since February 2015.
Argus suggests it is a 'point of vulnerability' that as it goes public on the New York Stock Exchange, Fitbit has less than 50% of the whole wearables space. But considering Fitbit only has one sports smartwatch, the Surge - that hasn't reviewed terribly well - this isn't surprising. Especially now that the Apple Watch is now on the scene, and if estimates are to be believed, dominating sales.
It's often tricky to get a grip on how many people own wearables worldwide but Fitbit announced recently that it has sold a total of 21m fitness trackers since 2011.
