I've had the opposite experience. I've bought each gen of the FitBit. I never found the new version compelling enough to buy immediately (but that's generally how I feel about phones and computers, too). I think gen 1 had the strap break after a few years (it was annoyingly wasn't replaceable). Gen 2 did suddenly just die after a few years. In both cases the newer version had been out for awhile and competitors didn't look too compelling. Each upgrade was nice, too. I did have a charging issue, but it was because I left the charger plugged in inside the bathroom. I guess the steam from showers corroded the charging posts causing them eventually to no longer make contact with the watch. I bought a few replacements from Amazon for <$20 total and started unplugging it when it wasn't charging and I haven't had the issue in years.
