Earlier this week we reported on the incident of a woman in Milwaukee, Wisconsin who allegedly had a Fitbit Flex 2 explode while on her wrist, sending her to the hospital with second-degree burns.
Dina Mitchell told ABC News that the device burst into flames without any prior indication, and that she had to receive treatment to remove bits of plastic from her wound.

Fitbit told us at the time that it had spoken to Ms Mitchell and was "actively investigating" the case". The initial investigation has now concluded, and Fitbit tells us it discovered the Flex 2 "did not malfunction" and that the damage was caused by "external forces" to the device.
What those external forces were is unclear - we've asked for some clarification - but as we said earlier this week, this was an isolated case, and Fitbit says it has not yet received any other complaints of a similar nature.
Here's the whole statement:
"We were greatly concerned by Ms. Mitchell's report and took swift action to understand the situation. Based on our initial investigation, including testing of her device by a leading third-party failure analysis firm, we have concluded that Ms. Mitchell's Fitbit Flex 2 did not malfunction. The testing shows that external forces caused the damage to the device.
We have not received any other complaints of this nature and we want to assure our customers that they can continue to enjoy their Flex 2 and all Fitbit products with confidence.
The health and safety of our customers is our top priority and, as such, Fitbit products are designed and produced in accordance with strict standards and undergo extensive internal and external testing to ensure the safety of our users."
For Fitbit, this is the first reported case of a Flex 2 exploding, and the device has been available for several months. We'll continue to watch the case closely - there may be more investigating to come - but it seems there's no reason to be concerned about your Flex 2 device exploding.
