I've bought every new version. I'm wearing charge6 now. ALL of them go bad in less than a year. I bought this version at the end of last summer and it's already giving me grief. It won't sync with my app anymore. I can't reset it by holding the side button down, like it says to do. My wife has been telling me not to buy any more, three purchases back. I like the thin, less bulky style on my wrist, but I guess its time to listen to her... at least on this one, lol.
