Does exactly what it says it will do
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Simply - the product does exactly what it advertises - it tracks the things it say - it communicates to my phone -- it does require more frequent charging than I expected - but it made no claims there - worth the price.

Love my FitBit
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The Fitbit reinforces my commitment to eating well, working out, drinking enough water and getting enough sleep. All the things that help you with your energy level which keeps me fit. Waking up with the FitBit is relaxing, the gentle vibration not only wakes me but my husband as well. Fitbit also sends me email each week with my updates. If you are health focused, this will keep you motivated to stay of course and meet and exceed you goals. Couple it with the My Fitness Pal and a running app and you are good to go!

Great tool for tracking steps

Love it!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I had the FitBit Force and did not have any skin allergies from it and loved it. The band started coming apart from the display not even 6 months after I bought it, so I went ahead and sent it back in for the recall refund. I purchased the Flex and I absolutely love it. I miss the display, but I always have my phone with me and can check steps on my app on the phone. I like the slimmer size as compared to the Force and I love being able to change out the band colors. FitBit also has excellent customer service.

Easy to setup, easy to use, easy to sync.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Device is easy to setup, easy to use, and easy to sync. Website dashboard straight forward. You do have the ability to make manual entries on the website. I found that to be not as straight forward however. Good forums should you encounter something or just want to get a question answered. For me it's been a fun motivator. I'm pretty competitive so I always try to out do my current goal setting.

Excellent fitness and weight loss tool
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This is 2nd one I've owned, lost first one. Using this along with 'My Fitness Pal' for activity and food intake tracking has helped motivate and remind me to get up and move about during the day. Silent alarm feature works well. Only draw back is weakness of wrist bands at the transition joint, though manufacturer is good about replacing bands.

Fun start to getting healthy.

Overall a great help for my fitness routine
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Overall, this has been an enormous boost to my fitness routine; especially when combined with the Fitbit Aria wireless scale. Charge the band, put it on and simply forget you are wearing it. The only slight issue I have is the sleep function. You have to manually "place" the band into sleep mode and manually "wake" the band. I think that as sophisticated as the sensor is, they could make the band to sense this on its own.

Pink band is lively, but gets dirty easily
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I love the pink band, which is bright and lively. It does get dirty quickly -- the darker colors probably get just as dirty, but the dirt does not show.

Good product but returned
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I did like this Fitbit. Linking it to my iPhone was a little confusing since their was no directions and had to Google them but once it was set up it was super easy. I did end up returning it Only because I wasn't a fan of the rubber band on my wrist, it kind of annoyed me. I have since gotten the Fitbit one that clips on to a bra strap or pant loop, which is also awesome.

Good product, can be better!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased the Fitbit to help me keep track on the activity level I have on a daily basis and to help gain insight into my sleeping patterns. This has help me understand the impact of the foods I eat and the amount of activity I should be partaking in on a daily basis, which helps me rest better at night. Overall good product but in hindsight I should have purchased the model with the digital readout.
