    Love my fitbit....I am a terrible sleeper and this was an easy way to actually record how many times I wake up a night...Also like that it can tell your level of physical activity instead of just steps taken

    I've been using a fit bit for about 6 months now, I got one for my wife and kids and my in laws got them too. Now we are all competing to out step each other. It's a fun way to keep motivated to keep moving.

    Started with the Zip and upgraded to the Flex. You don't have to switch with clothing changes since it's always on your wrist. Love the USB charging feature -,no more batteries. Easier to sync than the Zip.

    The fitbit Flex was exactly what I was looking for. The small size is great (I avoided the Force due to the larger size) and lack of screen isn't an issue for me as I prefer to open the iPhone application to check status. I use it to track my food and water intake as well. It has been very accurate for me as I compare it to my runners app after each run. Wasn't sure I would like this when I opened for Christmas, but it has been a great companion to my other apps used to improve heath.

    The device itself works great. We purchased it about a month ago and are very happy with it so far. It motivates us to eat right as well as take an extra walk around the block when we have not hit our goal.

    This is a great fitness tracker at a great price. Form factor is excellent, not to small not to big, comfortable to wear. Only complaint would be the sleep functions are quite as good as Jawebone.

    I love this device, I use it daily and I use it as an alarm clock now. I love that I can track my steps and I don't need to remember to clip it on or anything as I just always were it. The only thing that is a bit annoying is that when you are pushing a shopping cart and the cart vibrates, like when you are walking it out to your car, it puts the Fitbit into sleep mode.

    I GOT THIS TO TRACK MY SLEEP MOSTLY, BUT FIND I CHECK THROUGHOUT THE DAY FOR HOW MANY STEPS AND CALORIES TOO. WEARS LIKE A BRACELET SO I DON'T EVEN PAY ATTENTION TOO IT BEING THERE. NOT BULKY OR IN THE WAY.

    This works much better than the previous versions I have owned. The battery lasts about 5 days for me. Only small complaint is that the wake-up alarm is sometimes hard to stop.

    Great battery life compared to my last fitness tracker. The wireless sync is a great option too. Had a jawbone before. It lasted about four months before it wouldn't hold a charge or sync with phone.
