    . Encourage friends while competing with them! ! I love being able to use while in the pool during water class. It goes everywhere I challenge myself making my choices to walk purposeful.

    Fun For A While

    I was excited to get this but I think the appeal is short lived. I'm about a month and half into it and I'm a little more conscious of my steps but not as much as I was in the beginning. It's very hard to put into sleep mood after about a week of wearing for some reason. You have to sit there and basically bang on your wrist to get it to go to sleep. Sometimes it goes to sleep when you don't want it to which is funny.

    I recently started working out again, and pairing my Fitbit with MyFitnessPal app helps me track caloric input and output. It also tracks my sleep patterns. I'm addicted to this device!

    this should be a product given out to all students in high school or college to learn to begin tracking their health and physical fitness levels - its great when you are already in the mindset of daily checking up onyourself. love that it autosyncs and I can read progress data online. wish it wasn't bulky, even the smaller one still has that thick silicone spatula feel to it, I would prefer it to be even more discreet.

    I have purchased 3 of these devices. One for myself, my husband, and my mother as a gift. They are easy to use and wear, and appear to track steps accurately. However, all three of us have had issues with either not syncing or dying and not turning back on. They were all about a year after purchase (give or take). Luckily I bought the protection plans and exchanged them for new devices, which have not had any issues!

    I like using the fit bit for steps and sleep patterns. Haven't taken advantage of other features yet. Would definitely recommend!

    I enjoy my new toy more than I thought I would. My sister and niece have one and there is always a challenge issued. I will probably upgrade later, and I have also lost 5 lbs.

    I've tried quite a few devices to keep track of daily steps and activity. This is the first I've found that accurately keeps track of these and other measurements. Very useful little device.

    Love this FitBit. It's everything I needed to track my health. The sleep tracking is really great. Never knew how many times I was restless. Now to find a solution for that!

    I like that it holds me accountable for what I put into my body and it reminds me to move more! I get to chose a goal and because it keeps track of it I'm forced, thankfully, to achieve it!

    I am looking to lose weight with my husband. So we got these to compete against each other. It really does make you want to walk more. You can keep track of sleep, food,water. Kids LOL...

    I've been interested in the idea of wearable tech for a while now, and the Fitbit Flex has turned out to be pretty useful. I don't believe it's the most accurate device in all of the things that it does, but the fact that it's with me (and its app is with me) all day long makes it so much more useful than previous attempts at wearable fitness gear. If you're serious about something like this, you're probably trying to pick between the Flex and the Jawbone item. I think they're both excellent choices, for what they are.

    I call this my trainer. It keeps me honest. So many times, it is hard to keep track of diet and exercise. This is a tool that puts it all together, keeping track of ones activity and sleep.
