    The Fitbit Flex remains the premiere fitness tracker. I would only give it four stars though due to it's cumbersome and difficult-to-adjust wristband. I have found some aftermarket wristbands through French Bull that are much easier and work with the flex very well.

    Nice companion app, seems to be fairly accurate. The band is comfortable and you forget it is there most of the time. Would be 5 stars but the sleep tracking is spotty at best, and the diet tracking portion of the app is a pain and not really worth the time investment.

    A great idea for those who walk and are trying to get healthy. Very accurate and easy to use. The app can be more dynamic. But it serves the purpose it was designed to do.

    Really easy to wear and use. Charges easily with my laptop. Online application is very easy to synch and record other things such as food, weight, BP,glucose or other things you want to track. Love that you can wear it in the shower too.

    The device is great ! However, the band holding the device is very difficult to attach. It requires more than one person to attach. The band needs a redesign ! I have called Fitbit Customer service and they sent me more bands, they were just as difficult to attach

    I got the flex to help keep track of my steps, sleep, and food intake. Starting to get healthier. It has helped me tremendously. I love that I can link with my friends and partake in challenges. This is a great product. I'd recommend to anyone. Also a lot cheaper then the apple watch. I love apple products but this was way more affordable for me.

    This is a great product fir those who want to lose weight. It tracks steps, calories burned, your sleep, and easily connects with other weight loss apps and websites. Forget to take it off for a shower? No problem! It's water resistant!

    Great little device, keeps track of steps very well. The website syncs well with myfitnesspal as well which is nice to combine with this device. The wrist band may scratch after some use but only if you work under the hood of cars like myself. The one thing that stops this product from getting 5 starts from me is the lack of bluetooth connectivity with my Droid 4. They quickly blame the phone manufacture for not supporting bluetooth libraries but that sounds more like an excuse to me. Check if your phone supports this device on thier list otherwise you'll be limited to the usb dongle that comes in the box for use on a PC.
