Just gave up on Fitbit, me and the wife had Charge HR's, they both had to be completely reset on a couple of occasions, my strap went and my wife's went into needing a reset every week.
Software was good, but I am not sure many of the devices are up to any sort of hard use, I got a band 1 when they sold them off, but once that wears out I think I will wait until the tech (Well the hardware) grows up a bit more like the old Timex watch I bought my dad when I left school 40 years ago and the thing still works.
Yeah, once my Band 1 dies - which I'm sure isn't far off - I'm just going to wait. These fitness bands are not nearly hardy enough. They're so fragile. I don't abuse it. I don't throw it into mud or salty ocean water. I don't put it in a toaster oven or a freezer. I wear it normally, exactly like how I used to wear my old Casio watch. Wipe off the sweat, keep it clean, don't drop it or torture it, but it is falling apart. I'm on my second Band 1, and that thing is falling apart again, just like the one it replaced (battery covers peeling, clasp is loose and jiggles, rubber strap is rubbing off into little chunks). My sister and her boyfriend both have Fitbit Charge HRs, and both of them had to get Fitbit to replace theirs because they were falling apart so bad. Fitbit didn't even question them or ask them to send in their old Fitbits, and that makes me wonder if the company gets a lot of these requests. And I think we've all read about the Band 2's band splitting issue.
I'm really hesitant on buying another one of these things, regardless if it's a MS Band, Fitbit, Garmin, Samsung Gear Fit, or whatever. They're not exactly cheap, and they don't seem like they can hold up to their expected manner of usage. I'm just going to go back and wear my old Casio and use my phone as a pedometer.
