I was so excited o get this, and I actually told about 5 of my friends that have been looking for health trackers. They were all waiting for what I thought would be a rave review, but it was far from it. The only thing it actually tracked was my sleep cycle, and it wasn't even accurate. It basically started when I got into bed (which I would read for ~30 minutes), and ended when I got out of bed (which I would read for about an hour after waking up). It never once tracked a workout, even though I trained it to do so. It never tracked my calories burnt. Basically, it did nothing that it said it would do. Save your money and the ridiculous "$25 restocking fee".
