Only reason to own one over a Garmin imho. I love fitness+, my whole family use it daily. If I could just break the stupid need to want to track that stuff, all in my own head I could go back to my much better Garmin and forget about the stupid AW battery life. I had a good one that lasted my 2 days but I stupidly took it off on holiday and put it in the safe without giving it another thought until the day I went home. Running it out and leaving it like that was clearly a mistake, since that point I now have to charge it every day. As apposed to my now 6 year+ old garmin which lasts me 14 days.
