    Good entry-level activity tracker

    I think the Fitbit flex wrist bands are great for someone who has not used an activity tracker before and wants to explore something new. I've been using mine for about a year and I love it. It helps me know when I'm being particularly inactive and encourages me to move around more. Since using it, it has also encouraged me to look into other more advanced activity trackers. This particular purchase was actually a gift for my sister because she borrowed my fitbit flex and also became interested. Regarding the product itself - the band is very durable and I never take it off except to charge it. The functionality is very basic and leaves you wanting a little bit more, but like I said this is an entry-level product. I think the price could be a little lower considering the limited function, but I think it is still worth it if it encourages you to be more healthy.

    It feels like I am wearing nothing. It is way comfortable. I love the information. I love the heart rate monitor. The battery life is good. You just have to remember to charge it when you can. I charge it when I'm in the shower. It will last 5 days. The program is easy. I exercise much more now that I have this band. Not too big.

    Have been real happy with the performance. Also appreciate the sleep tracking function, just forget to switch it sometimes. The only negative is that at times the battery drains extremely fast, had it happen twice so far in the month and a half of use.

    So easy to set up. Responsive yet can take a beating. Got it for wife for mothers day and she hasn't taken it off. Loves getting the signal for her step count each day that she tries to see how early it can happen. Great for those who can't consistently work out and rely on walking at lunch / playing around with kids to work up a sweat.

    I enjoy the challenges with friends- if anything it is so motivating to add steps into our day. I dont track my food, just steps but I find that I have walked alot more for the fear of coming in last place! I also love the "silent" vibrate alarm!

    Love my Fitbit! It is the most accurate fitness tracker I've had. It is water resistant so I don't have to worry about getting it wet. Battery lasts about a week. It is a little expensive but it was definitely worth it.

    This has been the best $100 that I've spent in a long time. I wanted to lose weight, knew that I could start walking, but just didn't have the motivation to do so after work. I've had the fitbit for about a month and now I'm walking about 52 miles a week. All of my goals need to turn green or else I don't feel that I have completed my day. Even when I'm feeling lazy I don't take the elevator to the 3rd floor break room. Someone's busy and can't talk to me right now? Great! I'll be back later, I need the steps. Added benefit: now that I'm exercising, I'm sleeping better. The sleep tracker also made me realize that I don't sleep enough. I used to think that getting into bed at by 11 pm was doing well. Now I can see that it's not enough sleep.

    I love my Fitbit. It has helped me to stay on track with my overall fitness. I love that i can track my sleep as well. It has been a great purchase. My only complaint is that the band has not held up. They really need to consider a stronger model.

    Fitbit is a good device, light and simple to use. Sometimes to activate the night sleep you need to try several times. Overall I am satisfied with the device. Synchronization with phone is very simple and info available is good and seems accurate.

    I decided to get a fancy pedometer and I had a few friend who had fitbits so that's why I went with this brand. I have had my Fitbit for about a month now and absolutely love it. It has a a ton of great features that have helped me lose 5 lbs so far.

    My wife bought me one of these for Christmas and liked it so much, she went back for one of her own. Simplicity is what is great about this device. The app works well in tandom with the Fitbit, and it helps with daily accountability and goals.

    Never have I been so aware of everything that goes into my mouth and every step I take. I've learned so much about my eating habits and need to get off my butt and get out there. It's also shown me some things about my sleeping patterns at night. I really recommend this if you just need that constant reminder to keep on track.

    Not much to say about the Flex, it's decent if all you need is a basic activity tracker. This is the second one I have bought since the first one stopped working after about a year. The App is well made and easy to use and the battery is good.
