    This tracker stays on and holds a charge for days. It is a little tough to take off but that means it holds on well during exercise. I would absolutely recommend it so long as you don't want a display.

    I purchased this as a gift for my wife for Christmas. She had been wanting this particular Fitbit for some time now as she has lost a couple other types of activity trackers recently. She loves it.

    I bought this fitbit mainly because I wanted to keep track of my daily steps. It offers so much more. I love the features and the weekly progress reports. Lived up to my expectations.

    We bought this Fitbit for our daughters for Christmas and they love it. It is slim and not bulky like several of the others. They also got several interchangeable bands. The price was great for younger kids.

    I do not like this as well as the Fitbit Flex. Gives inaccurate steps. I can walk 4 miles but will only give me 3.5. Have to charge at least 2-3 times per week. For the price- I wish it was more accurate.

    This Fitbit Flex was great until it fell out of my pocket and I lost it. It also really sucked to log onto my status and see the person's status who found it.

    This purchase was to replace another that was covered under replacement insurance. Simple to use, links to iPhone app. Just wished the battery didn’t need to be charged every 4 days.

    I got this Fitbit for my wife. She had the fit bit flex but wanted this one because it was waterproof! She loves it the alarms alert her to calls on her phone when she doesn't have it with her. Great buy!

    The flesh 2 is great. The only fault, as with my old fitbit is that is doesn't like to sync. I had the part from my last one that goes into the computer for wireless, it helps but still has issues syncing.

    Good but has flaws

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This was a gift for my wife who wanted an activity tracker since she often doesn't have her phone on her during the day. She also wanted one that was waterproof for swimming in our backyard pool. It's been good for those things but the step count has been off compared to her phone with the Fitbit sometimes recording 3,000 steps vs phone recording 8,000 steps. We think it might be due to pushing a stroller and not having the arm swinging movement for the wrist band to detect the steps. Either way it seems like a fairly big flaw for the biggest brand in activity trackers.

    The Fitbit performs pretty much as advertised. The only glitches are that the lavender band bleached out in a salt water pool and it doesn't take into account my water exercise class and water volleyball.

    I had the FitBit One for years and happy but got interested in this one for swimming. I love being able to wear it during my parent/child swim lesson and can't wait to wear it when we swim this summer.

    I got this fitbit for my father on sale and he loves it. I got two so my mother could join in with his exercise and they can track their progress. Very happy with it. Basic but easy for them to use.

    It's great. I mainly purchased it because its waterproof. I wanted a Fitbit that I could wear at the hospital and not be concerned about it getting wet when I washed my hands all the time.

    I love it. I wish I would have gotten the upgraded version. But I will upgrade it at a later date. It vibrates with notifications for texts. It does what i need it to do and I can challenge friends.

    I owned the Fitbit Flex and enjoyed using it. Thought it was fine until I got the Flex 2. It allows me to wear it in wet situations. I love that the band is nowhere near as bulky as the Flex.

    Very happy with this tracker, I did not need all of the extras the next model up has. I get to track steps, sleep and get notified on band when I get a call or text. Perfect for what I need.
