Customer Ratings & Reviews

The band is comfortable to wear and easy to set up. The app is very good and tracks my activity accurately.

I haven't been using it for long, but it's interesting tracking steps and sleep. I exercise quite a bit, but this is encouraging me to walk more as well.

The FLEX work amazingly well and the battery life lasts a good 5-7 days before needing to be charged. Has built in vibration to let you know when you reach your daily goals. The silent alarm in the FLEX works 10 times better than my alarm clock. for some reason it just fully wakes me up in the morning rather than with my alam clock where I would just keep hitting snooze. The device is water proof so I can wear it all week long and only take it off when charging. The box brings 2 wrist band sizes, Small and Large.

This is probably my 4th Fitbit Flex; not because any problem with the unit itself but because I have given them to my goddaughters to use. The Fitbit company is excellent to deal with as I actually lost one of my Fitbits when I didn't realize it had fallen off my arm and the company did not hesitate to send me a new Flex. Because I wear mine all the time, my only complaint would be the look of the Flex. I wish the band looked nicer and had an actual clasp instead of the plastic push clasp. What I find it does for me is to push me to move more and certainly to drink more water.

Love my Fitbit. I use for daily walks and some running. Love that it keeps track of steps taking for the day and when activity is at the highest peaks.

I bought the Fitbit to track my activity and sleep. It does a great job and the cell phone application provides a daily read out when I sync (or you can choose to sync continuously that uses previous battery). It seems reliable as it compares of other tracking devises I have had in the past. It is super easy to use and I like the flexibility of the wristlet. It looks nice with whatever I wear. I have learned a few things about my habits and myself that I did not know before and find the information very useful.

I love my fitbit! I received it as a gift and wear it every day. It is nice to be able to track sleep patterns. Being able to monitor steps helps to get me out of my office during the day and move around.

This has been a great tool in helping me monitor my daily routine in hopes of becoming healthier. It really is fun to see all of the steps you take in a day and how many calories are actually burned vs intake.

I had a flex for several years, and it finally died. I replaced with the Surge. I HATED it. It fit poorly, the heart rate monitor bump HURT (like it felt like it was giving me bruises), the watch had to be worn too high on the arm, and snug (not fun when you are swinging your arms, you have to keep repositioning it). So I went and got another Flex. I just wanted something to track daily movement. I'll wear my HR chest strap and track it on my phone for my runs and very active workouts. The Flex is perfect for just tracking everyday movement and sleep. I didn't need all the bells and whistles of the Surge, I prefer the Garmin for actual running, and wear both the Garmin and the Flex when running. For everyday, it's perfect.

This little device has been such a great motivator for me. It stays charged for a long time & it's a nice small size for my wrist, of course, it comes with a 2nd band for a larger wrist. I LOVE, LOVE, LOVE it!

I received a fitbit flex as a gift and I loved it so much I bought this one for my husband. We have them synched with our smartphones and challenge each other every week to see who can get more steps. The flex has helped make us more conscious of our health habits and has helped us lose 30 pounds between the two of us in the last two months. I highly recommend the fitbit flex or any of their other products. The charge lasts for nearly a week and the bands are very comfortable to wear.

I needed feedback on my daily activity. Found it in Fitbit Flex. It tracks all movement, day and night. Results update to smartphone through wifi connection. Now I can see an accurate account of movement throughout the day - even graphs intensity of my activities. It's so light I forget it's on my wrist. And it has a social function - add friends and send and receive updates and encouragement automatically.

This is my first step tracker so I have nothing to compare it with, but overall I think it's pretty accurate. I do water aerobics and swim laps three days a week. The Flex gives me a pretty good estimate as to how hard I've worked out. I especially like the the information on my iPhone of the activity levels. The flex doesn't seem to track the strokes when swimming but it does a good job with the water aerobics and walking. I definitely would recommend it to a friend. It's a great motivator to keep moving!

I am glad I opted for this versatile tracker instead of another run of the mill pedometer. It provides incredible accuracy in tracking steps per day, as well as the convenience of tracking calories eaten or burned.

I bought the FitBit for my wife for Christmas and she wears it everyday to monitor her steps, sleeping habits, etc. She loves and she says that it keeps her informed as to what her fitness is on a daily basis.

Wish it was a little more stylish but it works great! Battery lasts for long periods, not alot of charging. Glad I chose this one..user friendly.

I bought one of these 2 years ago b/c it is the only one I could find that was water resistant. I teach swimming and needed something I could wear in the water all day. My first one had to be replaced 2x's (I bought the warranty and it was a breeze). After that, it lasted a full year and then in Dec it quit again. The warranty had run out, so I bought a new one. It never quite worked properly and a couple of days ago stopped functioning. I had it replaced today and hope that this one will work. I do have the replacement plan, so I am not too concerned.

I bought this unit to track my sleep pattern but wound up loving it for tracking food intake and calories burned. I'm hooked. I've lost 8 pounds in 4 weeks andlearned a lot baout where my caloric intake is.

Got this for.my wife and she uses it daily to keep on track with her physical activity. Allot smaller and more convient then some of the fitness trackers out there. Super easy to set up on your smartphone.

I bought this for my active wife!! She loves to see the number of steps she takes on a daily basis and logs in her food with ease! In the morning she loves to see her sleep patterns!! She loves her Fitbit!!
