Customer Ratings & Reviews

To keep track of steps, sleep and alert you to incoming calls this have a very good cost to feature ratio.

Purchased the Flex 2 to replace a 2 year old Flex (1st gen). The Flex 2 is great and offers more features, the only difference is I've found that the battery life is a little shorter and it takes a little longer to fully charge. Not sure why that is, or if it's just my particular unit. Overall, this product is great for it's size and weight. If you don't want an info display on your wrist this is the right choice. If you're looking for time and stats then upgrade to the higher models.

For what I was looking for, this is a great product. I needed simple, black, waterproof, inexpensive, but able to give me comprehensive data when I need it. The last part doesn't come from the unit itself, but the fitbit app on my phone. And since I generally have my phone everywhere I go, it isn't as important to me to see the data on a watch face. And that's what keeps it inexpensive. I like that it charges pretty quickly, too, and lasts about a week before needing a new charge.

This is a replacement for my older Fitbit Flex and I'm very happy with it. I added swimming to my exercise program and couldn't track it. I can wear this in the pool which gives me a more accurate activity total for the day. I have only had it a couple of days and there are more advanced features than my old Fitbit but, I haven't used these yet. I love the smaller size and that the clasp is so easy to fasten and yet, very secure. The lavender color has a touch of gray which is pretty.

I want expecting much for low price of this Fitbit. However, I couldn’t be happier. Great product. Especially since I prefer regular watches during the work day. I can wear this as an accessories.

Overall this does what it says it will do, I'm over the hill and the Font is a bit too small for me but it works, product is light and useful

I had a Jawbone up3 and really liked it. I would have gotten another when mine started fighting with me to charge, but the company isn’t doing wearables anymore. I have heard raves about Fitbit and compared the Flex 2 to other waterproof devices and decided the Fitbit was for me. When I do water aerobics, it tracks it as swimming - cool! I would recommend it to anyone who wants a tracker and doesn’t care that you can’t answer your phone with it!

Love how slim profile this fitness tracker is. I've owned one myself for over a year, and purchased this one for my girlfriend. They are very light, resilient wrist bands. An added perk is adding friends on the FitBit app so you can compete over who is the most active. Certain people mentioned above take this very seriously. Favorite feature is the sleep tracking. I use this regularly to see how much I've been sleeping and if I'm getting enough.

Since I don’t need all the bells and whistles offered with most high-end trackers, the Fitbit Flex 2 is perfect for me. Price was the best I’ve found! Service at Best Buy was excellent.

I actually made it a point to start exercising more, and something like the Fitbit Flex 2 was a good addition to my workout! It tracks how much exercise I get in a day, how much sleep and how well I sleep, and it helps set goals and keeps track of my weight! The fact that it's waterproof is a great plus since I live in Hawaii and swimming constitutes as one of my exercises! I just might complete the family and get the Fitbit Aria scale as well!

This product is the best. If you are looking for a fitness tracker and you don’t want to lose your regular watch, this is your product. BTW it is water proof that makes it even better.

Truly great product. Helps you with your fitness goals and is durable. The more expensive FitBit products have more bells and whistles but this one is water proof and much more durable.

I just recently received this as a gift. I enjoy tracking my steps and sleep. It is nice to have the reminder to move, and that it is water resistant so that it can be cleaned easily.

Love my fitbit! Tracks my steps and my sleep. Very accurate. Love the text alerts!!!

I bought this watch for my thirteen year old son as he was beginning to develop his muscles. He loves it and the fact that it gives call/message notifications it simply is superb!

This is a good improvement on older models of fitbits. It's much smaller and versatile than other versions. It fits about anywhere, and it's super easy to put in the different jewelry holders and such that are available. It does NOT have a standalone visual interface, so no watch, etc. You'll have to get all your info on the app and such. But, it's easy to wear and you can now make it match your outfit if you get the write accessory with it.

I wear this monitor with my Apple watch. I believed my watch was miscalculating my steps. This device and the watch seem to agree, but I decided to keep wearing it to monitor my sleep habits. While the sleep function is reliable most of the time, it will sometimes miss my first couple or last couple hours of sleep. Otherwise, it's light, easy to wear, and the ability to swim with it is a nice function.

Easy to setup and waterproof. Very accurate knows when im walking or doing other activities.

The flex 2 is awesome! It is super comfortable. When I wear it I can't even tell it is there. Also, it's completely WATERPROOF! I wore mine in the ocean and In the pool. Only reason I didn't give 5 stars is because It is said to last 5 days. That's cutting it. After a day and a half the battery went down to "medium". A device like this with no screen and just 5 LED lights should last significantly longer than 5 days in my opinion

Had to recharge battery every 3 days. It was supposed to last 5. Returned product and moved up to the Fitbit alta HR. Much better!
