    Bought one to replace an old Fitbit. Works great and is simple to use. My daughter wanted a fitness tracker, so I bought this one for her. For the most part, it is accurate. My daughter likes that it reminds her to keep moving.

    The Fitbit - Flex 2 Activity Tracker is exactly what I needed to track my daily activities. It is water proof so it's great for swimming. It even tracks my bike rides. It is small and comfortable and has a long battery life.

    I love my fitbit. It's exactly what I wanted. Small thin and tracks what I need and is waterproof. I am perfectly ok with only being able to see the results on my phone. I don't like bulky things on my wrists. So, this works well.

    The Flex 2 is perfect for people who want a simple device for step tracking. The Flex 2 shows me how well I slept and reminds me to get up and move on the schedule I choose. It keeps its charge for about a week. Band is okay.

    it’s an almost perfect band for the bare essentials. Love that it’s waterproof and that it’s thin and discreet. Literally the only thing it doesn’t do is count stairs climbed. Other than that I really do love it!

    Nice slim design. Can wear it swimming! And the battery charge lasts several days. No digital display, meaning you have to go to the app to see all your stats. That may be a game changer for some, but I don't mind it.
