    Really enjoy the feed back it gives about sleep. I like this a lot more than the Apple Watch to track calories burned. Only thing I’m not thrilled about is that the battery does not last a full 8 days.

    Excelent. I got it for my kid, and he loves it. Sleeps with it all nights and gets him the right information. He later uses the data to improve his gym routine as well.
