    After having this for a couple days I returned it for the up24. The main reason was the step count was very wrong. When I first put it on and after the second sync it said I took 100+ steps. When I really hadn't moved at all. The other draw back was the three day battery live. In order to charge it you have to take it out of the band and put it in the charger. In all it takes a minute plus to do this.

    Overpriced pedometer

    I was so excited to get the fit bit, as I had read many reviews and compared it to the jawbone up. One if the main reasons I wanted it was to improve my sleep. However, since the device is not accurate with that, I can't use it for that. I will wake up at night, roll over, look at the alarm, even reset my alarm, and it won't show that I was awake or restless. The only time it logs that you are awake is if you actually get out if bed and move. The food tracking is poor. I have to look up foods in my fitness pal and manually ad them. The calorie tracking is way off compared to my HR Monitor, so basically all that remains is a pedometer....

    Wore the Fitbit for a couple weeks and really like the style and the fact you wear it on the wrist not the forearm however it was not accurate for steps taken or calories burned. The calorie adjustment is the main reason I wanted it and it wasn't not even close to what I actually burn each day. Took it back and will likely go with Body Media of anything. That's what my husband wears and it works great!

    It will track everything as a step. I sneeze, 3 steps. I wave hello to someone, 25 steps. I walk a mile, 32 steps...

    It was too big for my taste as well as it didn't do as much as I hoped. I use another app already to log things, so I didn't want to have to log my exercise and food in the Fitbit app to fully utilize it. It only measures steps, no other activity so I found it kind of a waste. And it didnt track my sleep very well.

    Very durable

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I did a lot of research on fitness trackers before buying this thing. I wanted something to count my steps but needed it to be durable for the life of a zoo/aquarium worker. I work in an aquarium, but often deal with handling larger animals on a daily basis. Therefore- whatever I decided to buy and wear on my wrist 24/7 would have to be able to withstand a lot of water splashing & dunking, as well as stand up against a lot of blunt force trauma & scattered claw showers (because, let's face it, working with the unpredictability of animals does not always allow you the foresight or time needed to remove precious electronics from your body). So far, so good. When I finally decided on the flex, I went into best buy & explained my situation to the clerk. He was helpful in selling me a year (maybe 2 year? I should check on that) warranty in case my life decided to murder my new investment (I realize selling the warranties is part of the job, but I appreciated it nonetheless). I was skeptical, told myself if it died in the 14-day original trial run, I would return it and explore other options. I had a whole team of coworkers looking up to my decision as they wanted to get whatever I got, so that we could "compete" in friendly workplace step-counting. I have had this thing on my wrist since the beginning of April with zero complaints. I have recommended & managed to get about 8 of my friends & coworkers to get the same thing so that we can have challenges together. Out of my entire group, mine probably goes through the most rigorous tests. So far it has been: Slammed into a heavy door Dropped into the bottom of a salt water tank Stepped on Stolen by an iguana Licked by an octopus in 50 degree water Repeatedly dunked into buckets of delicious thawed fish water Swimming with stingrays Also licked by stingrays Touched by sharks Yanked by small children Etc & so forth I mentioned to a family member that I forgot to take it off during a snorkeling session & she panicked. Reminded me that it is "water resistant" not "water proof".... As a precaution, I now remember to take it off prior to snorkeling. But that is the only time that I remove it (aside from when it is charging). The step counter seems accurate, I have watched it move as I walk before, & while I may have some Italian blood in me (ie, I talk with my hands a lot) it seems to do a good job measuring my activity. I also enjoy the app & the fact that I can screenshot the end of a busy day at work to send to my boss in hopes of a raise or a "feel good bonus"... Still working on that. All in all, very great product. I got awesome customer service from Best Buy, & I managed to help y'all sell a couple more to the people around me. I truly hope that I do not jinx myself by posting this... But if you're looking for a tiny activity meter that can still accurately measure your activity while doubling as a mermaid, you have found your product.
