    I have been waiting for this for a while. My fitbit was barely hanging on because it was cracked in the middle and I was looking forward to having one around my wrist. I picked this up and immediately charged it and wore it for about 2 weeks. The battery in this does not last as long as my original fitbit but it's quick and easy to charge. But I misplaced the charging cable already and had to contact support for a replacement. This does not track steps and would have been a nice feature but I'm happy with mine right now and once my charger cable shows up I'll be able to use it again.

    Bought this tracker for my teenage college bound daughter to remind her to keep moving. She tends to sit to study a lot and not be very active so this helps her get up & go. It's also water proof and very comfortable for her to wear.

    Purchased this one for my 10 yr old to help her see how "none active she was". Since, she has set her a personal goal of 10,000 steps a day and consistently checks her progress to see if she needs more. Absolutely love this product

    I love my fit bit flex, because I dont have to worry about forgetting to take it off my clothes. I did that to my first fitbit One that was on my sports bra. did not survive the washer. The fitbit flex is just a bracelet I only take off to shower and charge

    FitBit Flex is a handy device

    I bought this device to help keep me honest on what I am eating, and how much I am moving. I have lost about 6 lbs. but hope to lose some more. I haven't have any problems with the FitBit Flex, but I understand they came out with a new version of this device about 2 weeks after I bought mine. Wish I had waited for the new one. When you log food, it offers suggestions about what it thinks you are trying to add. It would be nice if their database was a little bigger, as I have had to manually add quite a few items (like Sara Lee low carbohydrate bread). Overall, I like it. Also, It would also be nice to have a "pause" button, so that it doesn't record other physical activities as "walking".
