    This was a good basic step/fitness tracker. The fit bit app is great and they have added more features. The only problem I have had is sometimes it doesn't charge right. I may return and get a replacement.

    I had my Flex for a month now. The app is easy to use. So far I've had no issue with the band falling off. It says charged for about a week. I also enjoy the vibrate feature to wake me up in the morning.

    I bought this to replace my Force, which band broke, and couldn't purchase again. I found myself really missing the watch interface, so a Charge purchase soon followed. However, this one worked fine for tracking my steps, sleep, etc. Worth it if you like the minimal face.

    I bought this FitBit Flex for my wife, and I must say that we've both been very impressed with its performance. Never having owned something like this before, I was interested in how feasible it would be to track her activity and, I must say, it's pretty cool. Simple to understand, and you can take extra steps with the app such as inputting your calorie intake. Additionally, it was priced appropriately, has great battery life, and is comfortable and stylish (or so I'm told!). I'm sure it will become antiquated as newer generations of these devices come to market, but for now, the FitBit Flex is a great option for those looking to start tracking their activity and consciously monitoring their physical lifestyle.

    I had this exact Fitbit and unfortunately lost it. Reviewing my daily activity become second nature and I missed it. I didn't realize how important this device was to me until I lost it. It allows me to monitor my activity and stay on track...incentivizing me to stay active.

    My daughters and I gave the Fitbit Flex to my wife for Mother's Day. She loves it and wears it just about every day. She loves how it tracks her step goals as well as sleep patterns. She has already started a few changes based on her results. The band colors are fun too.

    This product is great for those that are not very active that want to get active. It has an app that helps you to track your daily/weekly steps, miles, calories burned, active minutes, water intake, sleep patterns, calories eaten, food plan, and excercise tracking. LOVE IT!

    We bought this for our 28 year old daughter and she really likes it a lot! It's easy to use and really encourages her to walk those extra steps and look at it as "opportunity" to meet her goals. She likes to check in with the details of her exercise and sleep. Great tool!

    I purchased this product for my wife and I purchased the Charge HR for myself. My wife liked the Fitbit Flex because it's not as bulky as the charge and you can change the style of the bands. She did not mind not having a display because she is on her phone constantly and can check her progress throughout the day. The tracker is pretty accurate as long as you don't do any vigorous activity with the arm you are wearing the tracker on; i.e. If you wave your hand, it will count steps. The only other complaint my wife has about the tracker is that it does not automatically track her sleep like the charge HR and you have to prompt it to do so. Other than that, it is a good product for the money.

    The Fitbit Flex is just the style my wife likes. It fits well and does everything she wants. It is easy to log her steps and the dashboard lets her know just how she is doing one her fitness program.

    Keeps me on track - I like comparing the days and weeks -being more aware motivates me to move more and it monitors my sleep and wakes me with a little vibration!

    I love it's light weight. I wear it 24/7 and forget I even have it on. Tracks my steps, sleep patterns and if I want, calories. I also use the alarms to keep me on time.

    Love this tracker, I forget I am even wearing it; and since I never have to take it off, I don't forget it. I have enough to remember and keep track of with 2 kids, the fitbit flex makes incorporating a healthier lifestyle easier. I love the sleep quality tracker and the silent alarm! The fitbit app that you can download with this has flawless integration and even allows to track calories and activities. I would recommend this product! My ONLY complaint is that it is not as accurate when I am pushing stroller (since it is worn on the wrist, but perhaps wearing it elsewhere during this type of activity might help).

    The fitbit flex is a reliable pedometer with excellent battery life. The iPhone app is great, the web apps are great (but expensive if you want to upgrade to the full experience), and the ability to connect with friends for challenges and badges is outstanding. The only issue I have with fitbit is that for a $99 pedometer, the fully-functional software should be free or a lot cheaper than $50/year.

    This Fitbit has become a part of me. The only time I take it off is to shower. Have become more active, and can monitor my sleep pattern. Also use to wake me up in the morning with a gentle vibration, no more annoying alarm clock. Would recommend this product.

    Bought this for my teenager. She likes that it tracks her steps so that she no longer has to keep her phone with her when she runs. It also tracks her steps throughout the day and her sleep patterns. It communicates with her iphone making it easy to keep track.

    I purchased this about 3 weeks ago and have worn it and used it everyday. I love that you can customize your goals (what you see and focus on) and that it tracks so much (steps taken, calories burned, activity levels and even sleep patterns). It was easy to setup but I had to reboot my iPhone to have it connect properly. I have been using another app, My Fitness Pal, to track my calories eaten for over a year so the fact that I can link that App to the Fitbit App is a bonus. (I find MFP has a more extensive food database.) I purchased it on sale and that made the price even better. I used the Help menus in both apps to figure out the linking of Fitbit to MFP. I recommend this for anyone who ever used a pedometer but hated wearing it... this is so much better and it gives you so much more information. Even if you are not a workout enthusiast you will like the motivation that this Fitbit gives you. Clasp can be a bit tricky at first but if you put your index finger inside and thumb outside and press it snaps in place. It has become much easier to snap after removing it a few times.

    I purchased the Fitbit Flex a couple weeks ago and have been very pleased with it. I think it fits comfortable on the wrist and is easy to use. I find that it helps to remind me to get up and move.
