    I purchased the flex because I lost my fitbit one in Las Vegas. My daughter had a Nike band, but that was more expensive. I miss the actual wording that the fitbit one had, but I am satisfied with the flex.

    I really enjoy wearing it, it encourages you to get more steps which I love. Almost like a challenge, or a dare lol - You can shower with it, sleep with it so it tracks your sleep. - however I don't always understand all the dots. But I'd still recommend this to a friend.

    Its great that it automatically updates, just lost one in the first week. So watch out to ensure the clasp is always connected. It would be great if they upgraded how the wrist band attaches to your wrist.

    This thing is great! It's easy to set up and use. Really keeps me on track throughout the day as I monitor my daily progress. I can also easily compete/compare with my friends that are fitbit users as an extra incentive to not only reach my daily goals, but to out do them.

    Love the Fitbit. Only problem is after a while gets hard to charge. This is my third one. I recommend getting the geek squad protection. It is helpful. Thinking of upgrading to the Alta.

    great at tracking steps. Doesn't seem to over estimate with arm movement. Wish I knew how to track my gym workouts as active minutes. Just need to read more online on how to work with the phone app

    I love my Fitbit Flex an even bought 2 for friends. It helps me to move more during long work days, and also challenges me during workouts. It's easy to use especially with the app. Fun to challenge others!

    We bought for our teenage son. He had been wanting to compete with us and several of our friends in challenges. Let's just say, he kicks our butts most weeks! It has been a great motivational tool to get him of the video games so much and out doing more.

    I always wanted a way to track my daily activities and with Fitbit it right at your finger tips. Amazingly you have the information you need or want to see how many step and track calore count you burn.

    The FLEX is ok for just basic purposes but don't overlook the Charge HR for only a few dollars more it is worth the investment to track more. The biggest problem with the Flex is that to track sleep you have to manually start the sleep mode.

    No, I would not recommend this to a friend
