In my case it was I found it on the ground. No one was around the band was broke it is a fitbit charge 2 $160 so I bought a 20$ charger for it and it works well. Downloaded the app made an account synced it game on. But I have heard you cannot replace the battery so when that dies your device does to. TBH all this could pretty much be done with a phone app and I am sure you can make something for the BPM that can be charged with your phone. Which would replace the fitbit completely for less the 160$ But i do like it.
