I have had mine since October of last year. I love it! Before my fitbit I considered my job and lifestyle to be lightly active to active. When I first wore my fitbit I swore something was wrong with it. However the numbers don't lie. Once I really started moving and increasing the activity it made ALL the difference. I have it synced with myfitnesspal because I use that for my food.

After having it for 2-3 years my fitbit bit the dust a few weeks ago. I LOVED it. I'm currently waiting on the release of the fitbit flex.

My husband and I just got started with our Fitbit. We actually got ours free through his health insurance and are participating in a 1,000,000 step challenge (to be completed by 12/15/2013). Our participation allows us to earn points which help to keep our health insurance premiums lower. Only steps recorded with fitbit count toward the challenge. I suppose you could say it is a glorified pedometer Coolhand. It automatically syncs wirelessly and records your steps throughout the day. It comes with a dongle which allows it to update anytime you come within 15-20 feet of your PC, or there are also mobile apps for smart phones, ipads etc. It records steps, calories burned, and distance. (Also shows the time). It is designed to be worn 24/7 and also records sleep patterns I believe. I am still new to it so haven't got it all figured out yet. So far I am excited about it. It has motivated me to get back to eating healthier and becoming more active. I have used MFP in the past and kind of strayed away but am glad to be back!
