After 3 Fitbit Charge HRs dying on me within a year, I've left FitBit and moved on to Garmin. It's a shame because my Flex was solid for multiple years.
I've had the exact same problem both with the Flex and then with the Charge HR. Their hardware quality is just terrible, especially given that they're expected you to pay >$100 on their devices! I now go out of my way to actively dis-recommend Fitbit (as I've done in this comments thread).
hmm, that is the opposite of my experience. My mom has an original fitbit and me and my wife have the fitbit charge HRs. I actually thought when I read the title that it was due to lack of demand as everyone I know has one and sees no reason to get a newer one.
