Customer Ratings & Reviews

First it's not compatible with my phone (iPhone 4) so I'm always syncing to my computer which isn't always convenient. I don't think it's always accurate. Not worth the money spent

This tool is a great way to track just how many times you walk in a given day and it measures your sleep. It motivates me to be more active, since I can see at the end of the day just how far I've walked and how active I was that day. It is an excellent tool, and I highly recommend it.

Very disappointed. Limited help written and online. App is difficult to use. Very frustrating. Was looking forward to using it from friends who have one. Sales person was not helpful or knowledgeable. Difficult to find any salesperson to help me. Seems like they like to talk to each other and not to customers. Probably will not buy at Best Buy again. Reviewing this site I wonder if anyone at Best Buy will read my review and/or do anything about it. Or is it just to be able to post reviews. We shall see,

Not good at all at tracking your steps or your sleep. Would have kept if there were a quick pause feature when you are driving so as not to affect your movement falsely.

Not enough instructions included on setting it up. The associates in the store did not listen to my needs to sell me the product that was actually wanted.

does its purpose but only when you can get it to stay on. Rubber bracelet is too stretchy. Falls off during basic activities, like running, which is contradictive

In order for this item to work properly, you have to spend too much time entering everything you ate onto your profile. It is too easy to hit the unit and accidentally put it in sleep mode and there is no way to tell if it is in sleep or awake mode.

I liked the bracelet so I could leave it on all the time but it kept adding steps while I was doing computer work

I don't have the box or I would return it! It doesn't track sleep right, says your resting while your wide awake! It track any type of machine workout, either weights or steps/elliptical machines, like the up! It doesn't vibrate unless you move it from sleep to non-sleep, so no point in that! Its easy to use but that's because it does nothing besides look ugly on your wrist! Thank you!

Summary says it all .. I considered getting a fitbit one next, but realized in terms of android it was only compatible with Samsung phones, so I got an S4 and it turned out the step counter.calorie counter was built into the phone in an app called "s health", so why did I need the fitbit again? Oh, if you have another android phone, there are apparently other step counter apps you can find.

Very difficult to latch wristband.. Very inaccurate step and stair counts. No screen to view progress. Not worth the money

The Good * iPhone app is very intuitive * Real-time access via app on your phone is great * Sleep tracking feature is very useful and works great * A lot of competing fitness wearables don’t offer sleep tracking * Offers both a small and large wristband in the box * Offers a silent alarm that works well * Lasts 5 days on a single charge * Auto-syncs with smartphone and computer (if Flex in within 20ft of the included Wireless Sync Dongle while plugged in) * FitBit community is thriving so you can always compete and get motivation from others * Online dashboard has a graphs and charts relating to the fitness tracker from your Flex * The smartphone app has recently been updated to include a barcode scanner to help track your meals * Meal tracking can be done manually * Flex can be worn in the shower so you really don’t need to take it off except to charge * You can purchase cool wristband colors separately for around $14 * You can earn badges for extra motivation * Sleekly designed * So comfortable you can forget it’s there * LED dots display readout of your progress * Uses Bluetooth LE * Water-resistant The Bad * Sometimes extremely generous with step counting * Proprietary charger * Doesn’t track stairs climbed like the FitBit One or the now discontinued FitBit Force * Doesn’t tell time * Premium users will get much more comprehensive comparisons and tracking stats The Ugly * Premium features cost $50 per year Recommendation: I would recommend the FitBit Flex to anyone wanting to get more active. It may be overgenerous with it’s step count but I know for a fact wearing it makes me be more active. I takes the stairs more often then the elevator and don’t mind taking a longer route when walking to add more to my step-count. I also convinced my wife to get the Flex, so now we compete.

This device does not keep a charge and also has sync issues after a couple of months. Make sure to get the Geek Squad Protection with this item

The flex, compared to prior products ie the One does not have the battery life needed for regular use. Also the watchband collects a lot of sweat during exercise which makes for not so pleasant smells which requires cleaning. The flex also only tracks motion as part of hand motion so if you're using a stair climber or an elliptical then it will not count those steps. So in short more cleaning less steps more charging so maybe you should just get a older fitbit one

I recommend it for walking as a pedometer. I thought it would track cycling as well. it doesn't, and sometimes when I'm driving my car, it counts steps.

i bought the fit bit flex to help me track my daily excercise and then set higher goals. but yet the fit bit will not update not even when it is plugged in and charging. constantly says cannot locate tracker when the tracker is a whole 4 inches away. on days that it does decided to sync it somehow doesn't log any steps i take. on average, and ive had it for about three weeks now it keeps track of my steps maybe 3 days out of the week.

I used to love this fitbit flex until the band decided to snap off. I would not buy a flex again, i would opt for an alta or charge

I've used it. It's very functional, and provides great information. However, after so long you'll get tired of having it around your wrist all day.

I purchased this but returned after 2 weeks as I found this to be very inaccurate. Not just by a few steps but by an entire mile.

Very difficult to close band. Have touse pliers as a result Ican't use the band. Waste of money on this
