Customer Ratings & Reviews

Useles. Used for one week and stopped. Waste of $100. Claims to be waterproof/water resistant but when I removed the device to charge it was wet (hadn't showered or went swimming for several hour) and it smelled horrible like a mold or mildew growing inside. If you get it wet you need to take it apart to dry out. I prefer my one tracker over the flex.

I like the fitbit, would like digital read though.

I like the flex one better., this was a gift for my mother and she exchanged it for the fit bit one.

Purchased this to track my calorie burn, calculation seemed off, returned for Polar.

it was not accurate and did not hold the charge!!!!!

Is not worth the money for as little as it offers.

It's ok, but could be better. The closure for connecting the back can be a pain to get connected.

This fitness tracker has a lot of good features, however it didn't track accurately.

Okay the Strivv died and now my Fitbit is dead... errf

I bought this for my son. He said it was ok but he wanted more bells and whistles

Good, but won't sync with Apple Health. I would pick a different model next time.

It has not been accurate in counting my steps! It has not been accurate in counting my steps!

It is comfortable and easy to clean. I don't like that the plastic fastener broke

Worked great in beginning, then stopped working when battery was put back in band

Did not expect to like but have enjoyed this item and look forward to using for sometime.

Already having to order a replacement. How frustrating!

Don't like that I have to look up the stats on my home computer. I went back to my fit bit one.

I only owned the Flex for a couple of days. I went on 3 walks, each 500 steps by my count. Once using my arms naturally with some swinging and some drinking water. Once exaggerating my arm swing and once with a natural swing but not using that arm for anything else. The Flex only counted about 400 of those steps for each walk. It also counted ZERO steps while grocery shopping because I was pushing the basket. When I emailed Fit-bit I received this generic response "Flex will count your steps when you're walking with your arms stationary, as we do want to give you credit for this activity. This includes walking while pushing a stroller or shopping cart, or holding on to a treadmill. That said, because your hands are not moving, your step count may be a bit lower during this activity." My step count while grocery shopping was not a 'bit' lower, it was zero. I returned the flex and bought the One and it is much better. It actually counts my steps, every step.

Great product. Just wish I could view my steps without having to open up the app on my phone.

Best item I got my wife. My daughter and son in law have one each. A lot of competition.
