Lightweight and thinner than the original flex. I like it. The only complaint is that I sometimes have to reboot the bluetooth, which is kind of a pain. I like the sleep feature, never knew I was so restless when I sleep.

I'm glad it's the only Fitbit that's waterproof. Thanks

Bought as a replacement for my Fitbit Zip (had the Zip 2 years and it eventually quit). Love this Flex 2. Use it for step, distance and calorie counting. Set the alerts to wake me in the morning (I also use the sleep monitor), but also set the alerts to ping me when I receive texts or phone calls. Combined with the Fitbit app, you can also use it to monitor exercise, water intake and calories. It took a few days to get used to the wristband (stopped wearing a watch many years ago), but it's light, comfortable and easy to clean. Seems you can also buy more fashionable styles if this one does not suit you. Box contained two bands (large and small). Unit is rechargeable which I like better than the battery-operated Zip. Very satisfied overall.

I love my flex 2. I bought it to check my sleep patterns and watch my fitness activity. Very happy with my purchase and a HUGE plus it’s waterproof since I groom dogs my arms get soaked! Definitely recommend!!

You can't look at the band to know your status you have to look at your app but I like this one best anyway. I have had 3 others in the past and this one is just a sleek band which is easy to charge and waterproof.

I’ve loved my Fitbit Zip but handed it off to my fella because it has a readout on it, whereas the Flex 2 does not. I’m happy to read my stats on my smart phone. It took a little getting used to wearing the tracker on my wrist instead of clipping it to clothing, but I’m very happy with the transition to the upgraded model.

Works as it should and the battery life isn't great.

I love my fitbit. Holds charge and keeps me on track

Great easy setup and u forget that you’re wearing it

My husband and I both got this model and both love it. It's waterproof so we never have to take it off we shower with it and wear it in the pool. I wish the battery lasted a bit longer but otherwise no complaints

Love the Fitbit especially since I can get it wet.

Love my fitbit...easy to set up...works great.....

This Fitbit gives you all you need to keep active.

I would recommend this product . Easy to use. Cheap

Bought this as an Xmas gift to replace gf's Flex that had died. She really liked the smaller size of this unit vs. the old one. She didn't seem to mind the loss of displayed time that she had on the old one either.

Great device, easy and simple to set up, satisfied

I think overall it is a nice sports kit. Light, battery long lasting,(charged once ,last 4 days). Water resistant, recongnize swim , sleep time accurately. I have Apple Watch, but I would prefer this over .

The Flex2 is perfect for me. It is light and I barely know it is on my arm. The batter lasts about three days. I am able to charge it at night so I don't miss any count of my steps. I love how it tracks my sleep.

I bought the flex 2 because I like to swim and wanted to track my activity in the pool. The flex 2 is great for that. The battery doesn't last as long as I hoped, about two days or so. Overall pretty great.

This has been a great tool to keep track of my steps, and to track my sleeping habits. I get reminders to walk and move, when I havent taken 250 steps in an hour. It encourages me to be more moble.
