Customer Ratings & Reviews

If you want to track activity and sleep, this is the product. It's easy to set up and use every day. You don't even realize that you have it on.

I haven't taken the Flex FitBit off!! I love it!!!

I have lost 30 pounds tracking my steps and weight

I got this as a gift for my mom. It is really nice all of the different features it has. I want to get one for myself now so that we can sync and compete with each other on our steps!

I give this product an 8 of 10. Tracks well and keeps me interested however I would like to see more accurate food and workout options added. I manually add workouts and don't get nearly the credit I should get with regards to calories burned etc.

I recommend this for anyone wanting to lose weight.

This was my second fitbit. My first one had to be charged everyday. This one started out working great and only had to charge once a week. I had it for about 2 weeks and it wouldn't charge.

Anyone wanting to track their activity will benefit.

I bought the bracelet (flex) and it quit working in less than one week! However I exchanged the bracelet for the fitbit one and I love it!!!! I clip the ONE on my bra or waist and I don't even know it's there! Love this tool for motivation!

I have a FitBit One and decided to get my husband the FitBit Flex for his birthday. Now I wish I had the Flex! It stays on so much better than the One and appears to have all of the same features. He appears to love it and wears it daily. We also got the FitBit scale (Aria) and it works great with that device too. Love it!

The FitBit One is much more accurate. With the Flex you are able to get steps by simply moving your arm. The sleep info is pretty cool!!

I am a college exercise enthusiast and was very excited to try out this product! I got it all set up only to realize it's so much more work than I expected. I wouldn't recommend this product, I'd recommend the more advanced Fitbit.

Works well for measuring day-to-day mileage, somewhat OK for sleep information. Doesn't report any climbing of stairs - although suppose to. Entering food eaten is problematic unless you always eat pre-prepared foods or at restaurants.

It generally does what it advertises. The sleep tracker is nice, but I don't always remember when I fell asleep / woke up in order to track it... Would be nice if that was more automatic.

I reveiwed several items before settling on the Flex to get my fitness program started. For the money this is fantastic and bought it at Best Buy for their price match guarantee. I saved $20 without having to wait on Amazon!!

This is a much more comfortable wrist worn tracker than my UP band. I don't even notice that I have this on. That said, the sleep tracking is neither as accurate or as useful as the UP. The Flex also lacks the smart alarm feature that UP has.

I like it. It isn't bulky and it doesn't fall like most odometers. The accuracy on steps is a bit off and the charging chord doesn't work well, otherwise I would give it a much higher rating.

Great step tracker and very easy to use. Great app.

This is a lightweight tracker and perfectly adequate for tracking basic functions but I wanted one that showed the time and this did not. So I exchanged it for a Fitbit charge

I bought this as a present for my husband but he ended up returning for a fitbit one which he thought would work better with his lifestyle. He loves all the features and seems more excited about staying healthy which for me is a great review.
