    I have had issues with my sleep. It seems it is no too accurate calculating sleep, just being still.

    The fit bit bracelets that hold the product are not good quality, they break very easily. How are you supposed to sleep with them and gauge your sleep if they tear extremely easily.

    Love the band and the concept, disappointed when it appeared to get water logged and broke. They incourage you to wear during the shower...so the band should be more durable!
