    Love the flex. I enjoy the tracking of sleep along with everything else. Already lost 7lbs in 4 weeks just by using this and tracking food and activity level

    I like knowing that I sleep more than I thought I did. It motivates me to drink more water so I can enter ounces drank and see what I've accomplished!

    Bought this for my girlfriend because she wanted to be able track her daily steps, down time, etc. She likes it so far and the program / app works well. I have concerns about the durability of the wristbands though because after only one month, the band started splitting and is no longer usable. I was pretty disappointed in that... She wears it 24/7 but it's not like she put it through any abuse other than what it's intended to be used for.

    We bought this as a gift for my son. Although the counter seems accurate there are a few negative issues. It has to be manually synced way too often. The toggle is inserted but it still needs to be manually entered. The instructions to do that took several attempts to figure out. The strap also causes irritation and he frequently removes it for that reason.
