I have worn the Flex for around a week now. It seems to be fairly accurate. I am a previous zip user and the numbers that I got from that device are around the same. I have read ALOT of reviews online, and it seems people are complaining that it calculates steps when waving arms and typing. Mine does not do this at all. In fact I have the app open on my desk and monitor it to see if steps are tracked when I type and they are not. I also drive 1 hour to work and 1 hour back every day it it maybe calculates 5 steps. My Zip did the same thing. I did however make sure that I wear it on my non-dominant hand and have the setting online set to "dominant". The dominant setting makes the devices less sensitive and maybe thats why people are have accuracy issues. Overall, I really enjoy it and it helps me reach my daily goal of 15,000.

Great Fitness Tracker
Posted by: acesavage from: Portland, OR on
FITBIT Flex was surprisingly light and feels good on the wrist. I was afraid it would bother me at night, but I found it to be comfortable. It does a good job at measuring my sleep times, step counts and activity. I have to manually record my swimming as it’s not recommended to submerge it for any length of time. The flex was also easy to setup and online software can integrate well with other fitness software like myfitnesspal.
Negative reviews seem to come from people who owned previous waist / pocket models of FITBIT. They seem to complain that it doesn't have a built in display or altimeter they are use to. It would be nice to have but I’d rather have lighter more comfortable wrist band then to bulk it down with those features. Why would one buy this product knowing it doesn’t have these features then give it one star complaining about it is beyond me.
If you are looking for a wrist band model, I would suggest the flex.

Not for anyone active
Posted by: oksikoko from: on
I'll keep my review simple and focused on one critical issue: the snap clasps which hold the device to your wrist are too easily opened. I had only had my Fitbit for a week or two when, while strolling through a store, I noticed it missing from my arm where it had been 20 minutes before. From what I can surmise, it snapped off as I pulled a shopping bag over my hand. A stronger method for keeping the band attached to your wrist, for example any of the types of clasps used on watches for hundreds of years, would make this a better buy. I'm sure the snaps were chosen by the designers for convenience of removal and frugality of manufacture, but anything intended to remain on the wrist during miscellaneous physical activities and sleep should have a clasp designed primarily to hold it on the wrist, not for easy removal. If I had had the Fitbit longer, I would be able to review more of its features. In this instance, perhaps uniquely, the fact that I lost the device speaks more to the value of the device itself than would be true of a device not meant to remain on my person.

Why I miss my Fitbit
Posted by: Rudy770 from: Spartanburg, SC on
The wrist band clasp is so flimsy that I never noticed when my 1 week old $140 fitbit fell off and got lost. So even though I loved it and loved the ability to see my daily movement at a glance or chart it on the browser. The joy and thrill was short lived, I thought it a bit weak of a clasp but foolishly trusted the manufacturers surely would have thought of this and maybe it just looks flimpsy, I'm sure there is a reason tehy had to make it this way. well I guess either they did not think it through or the intention was for the buyer to fall in love with what it does then lose it and have to go out and buy another. You know they've made wrist watches for quite a long time and the clasp is a bit more secure - maybe because watch makers don't want you to lose your watch during the first week after you buy it. Maybe a future version of the fitbit can come with GPS so you can track it down or they can sell them in a 12 pack or maybe - lets get radical and create a better wrist band!

Nice product but not the mobile app
Posted by: Patmi from: Michigan on
The Fitbit Flex is easy to set up and use. The web interface that displays your activity and data is easy to navigate. The wrist band is decently comfortable to wear. I liked it until I started to install the mobile app. I bought the Fitbit planning to use the Android app with my phone. Then I read the permissions you give the app when you install it including the following.
"Read your contacts. Allows the app to read data about your contacts stored on your phone, including frequency with which you've called, emailed, or communicated with specific individuals. This permission allows apps to save your contact data..."
What reason would they have to collect your contact information? If they collect that what else are they collecting and who are they sharing it with?

Great Simple Activity Tracker
Posted by: JenniW from: on
I was debating on what activity tracker to get, and I almost was going to get the Apple Watch. But then I realized how much I carry my phone with me, anyways, and I don't need all these apps on an activity tracker. Then it was between the Flex and the Charge/HR. I don't need a Heart Rate monitor, and I wanted to be able to switch my band color whenever I wanted. So I went with the Flex. It's simple to use u just tap it a couple times to see if you're close to your goal, or it starts vibrating and lighting up if you've reached your goal. And when you want to go to sleep all you have to do is tap it a few times and put it in sleep mode and do the same when you want it to wake up. But now with the latest update you don't even have to put it in sleep mode, it'll do it on it's own. This is the perfect activity tracker for me, and really it's all in the app, because you can track your food intake, and water intake, set a weight goal....all that from the app. So the app along with this little tracker that I can change colors whenever I want, it's pretty cool.

Must read directions on how to use it
Posted by: blazeoc from: sandy, UT on
So overall I am okay with the purchase. Price point is solid, website and tracking is solid.
I ran 7.16 miles this morning and when I came back to sync it, it only showed 6.7 miles. So not as accurate as it should be to be honest.
Slept with it last night and I would say the sleeping part of it was accurate. When I awoke I remembered to look at the clock to remember those times and when I looked at the report this morning it was spot on.
Again overall I like the purchase but do not expect dead accurate results. I don't think you should ever expect that from any of these devices to be honest.

Love this device!
Posted by: Sandy from: on
I received my first Fitbit Flex as a gift and immediately began using it! It is easy to use and it does challenge me be even more active than before I started using it! This was a replacement because I lost the first one after three months. I highly recommend buying s strap that has a buckle! The French Bull makes some cute ones! They are available at Best Buy!

Great Little Activity Tracker
Posted by: Gusa39 from: Long Island, NY on
I bought my FitBit Flex a few weeks ago and so far I think it's a great little activity tracker. For the most part it tracks my steps and calories burned as accurately as any pedometer would, but what I like about the Flex is that I wear it on my wrist and don't have to worry about taking it off and possibly loosing it. It is truly water proof, I wear it in the shower with no problems at all. I know it is very accurate when it calculates my sleep pattern because sometimes I make note of the times I get up at night and check it against the Flex the next morning. it's always on the mark. If anything it's a cool little device that will help motivate you to beat your previous days results. It's cool to see how many steps you take in a day, week and even for the month. It syncs on its own and has a great App for your smartphone. I haven't had it too long so I really don't know how durable it will be for the long haul. At first it's a little tough to snap it closed, but in time it loosens up and snaps on your wrist with no problem. I would recommend it

better than the jawbone
Posted by: zookeeperr from: Pa on
is accurate,easy to use,and water proof. wish the battery lasted a little longer before recharges. had a jawbone that only lasted for a few months before it died so this seems better quality. you get a fair amount of info from the wristband but you have to pay to upgrade the account to get more detailed info. if you got more detailed info without upgrading and further cost and a longer battery life I would of left a 5 star rating. all in all, it's good. the only real complaint is that certain vibrations in your hands can cause it to go to sleep. it went to sleep on me a few times just by pushing a grocery cart on rough asphalt and that throws off the readings for that day or until you realize it is in sleep mode.
