    A good product.....with reservations

    The Fitbit Flex is a great idea and a quality product. However, be careful to check availability of your phone against what the Fitbit works with. The advertising says iPhones 4 & 5, iPad, and "Android Devices". However, it only works with 4 very specific Samsung phones. I found the clasp hard to close. Best Buy was great about returning the item and I bought a Jawbone UP which is, IMO, a better product.

    Poor Design

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I purchased one of these for my mother and one of the black ones for my father. The bands are difficult for many older individuals to fasten themselves (Up by jawbone is a better band for those with limited dexterity). The display on phones for sleep pattern are poor, there were no instructions included with the device, I had to go online to find info to help my parents figure out how to work it, and then with trying to remember to tap repeatedly while watching for certain lights to light up, is just insane. I ended up trashing these and getting them UP 24's Much easier to work with.

    Functional and affordable

    Great activity tracker, includes multiple band sizes for convenience. Larger than the UP2, somewhat difficult to fasten band, but has LED lights to show your progress to goal throughout the day.

    Loved it for the first month.

    I bought it about three months ago. The devise was good and the program is really good, I like the user interface and what not. Charging the devise is a pain because the charger is loose and you had to wedge a paper in. My first charger broke and the manufacturer sent me another. Now the band is ripping in the bottom and and actually hardware is pealing. I should have gone with the jawbone up.

    Extremely Inaccurate

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I was so excited to get my Fitbit Flex. I had read reviews that it was inaccurate, but also saw that there was a way to overcome this by calibrating it. I got it home and set it up and was so disappointed. I tried calibrating it and thought to give it a second day. However it told me that I had already taken 50 steps before I even got out of bed! If it was that inaccurate before I got out of bed, I cannot imagine how inaccurate it would be wearing it throughout the day. If the product was only about $30, I would expect the inaccuracy. However, for the price I would think it would not have this much of an inaccuracy. I am bringing mine back today because I am so disappointed.

    Bracelet is poorly made

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I love how easy it is to sync up the Fitbit. However, I have had the Fitbit for a little more than a week and both of the bracelet's broke. I was not aggressive in taking out the Fitbit from either bracelet. I am so disappointed . I will be returning it over the weekend and trying a different brand. I have emailed the company and I am still waiting for a response. I read a lot of the reviews and I really do not see anyone complain about the bracelet :(

    I've had the fitbit for a week and really like it. It's a nice reminder to stay on track towards goals and is comfortable to wear. I recommend using myfitnesspal for food tracking - easy to link the accounts and myfitnesspal has a better food database.

    Charging

    Not a serious company

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I got FITBIT last year and even not being very comfortable for the lack of display ; I was able to use it; however, charging food was not that easy and statistics are not always reliable. However, the worst part came after three or four month the unit started having problems when charging. A couple of times, I left it connected to the USB port and next morning the unit was dead. A few weeks ago; it basically stop charging even changing computers; cleaning contacts and doing the recommended reset. Customer Service took over 24 hours for the first answer and about 24 to 48 hours for the following responses which basically was asking if I performed every possible suggestion in their Web site. After almost a week back and forth, they ask me to send the unit plus the purchase receipt so they will check it and if the warranty was still valid, perhaps replace it. I told that after a week of losing my time; I did not want to expend another two weeks waiting for somebody to decide for a replacement. So if you expend $ 100 or more in this tracker; and fails (something according to other reviews happens very often), be prepare to interrupt your training until this people decides to help you. In brief; look for a more serious company

    disappointed

    I also have been waiting a long time for this, and went out at lunch time to get it. When I got home and synced it and went on a walk, I realized the flaws that I was worried about. First the step tracking was way off. I wore my fitbit zip to test it out, and after an hour the flex was under by about 400 steps. The other major thing that I couldn't get over, there is no display. I have a hard time putting so much trust in it syncing, even after all the syncing problems that I have had recently with my zip. The clunky sleep function and the lack of floors climbed option were other minor annoyances.

    Great Reviews, IDK

    I purchase this product after reading reviews about how good this product is and how easy it was. Well after purchasing this item, went home and try to set it up, no manual at all and even the FAQ's online didn't have much to go by. I was not sure if the product was even turned on properly, I walked around and even jogged to see if it works and nothing. It's so sad because this product has really good reviews.

    The Fitbit is great! It is everything I was looking for. I love the that it connects to my phone as soon as I open the app. I had purchased the LG life band first and returned it after 2 days due to not being accurate. glad I did!

    It was good while it lasted

    Day 1: I was a little skeptical as to whether or not I was going to find this device to be truly useful. Set-up was a breeze and started my fitbit journey. Day 2: I was starting too really like this tracker and was finding the data to be quite useful. Day 3: I liked it so much I started thinking about purchasing a second one for the wife. Day 4: All was good at 6AM tracking and syncing like a champ. Then comes 9AM and I find the tracker to be completely unresponsive. My first thought was that the battery must be dead so I got out the charger and charged it up. The first thing that I noticed was that not all of the LED’s seemed to be working since the tracker was now displaying “O_OOO” instead of “OOOOO”. The second thing that I noticed was that I was no longer able to connect and sync the tracker with either my phone (Note 3) or my PC which both had been working up to that morning. I tried everything from cleaning the contacts, resetting the device with a paper clip, uninstalling and reinstalling the app with no success. I just can’t get this thing to reconnect to any device and through this whole process the fitbit tracker became completely unresponsive again as if the battery was dead (only about 1hr later). At no point did I shower with or submerge the tracker so the only fluid that it would have come in contact with would have been sweat during exercise or from getting splashed while washing hands. I have since contacted Fitbit customer service to see about getting a replacement unit and have only received a semi canned response telling me to try doing all the things that I have already done. Hopefully they come through and if they do I will update my review. I did love this tracker while it worked but I can’t recommend anything that only lasts 3 days.

    Great idea! Terrible, terrible execution...

    The Fitbit customer service people are very nice. This is fortunate, as you will talk with them frequently to replace defective units--so far, two replacements for me, owing to defective batteries. Moreover, the wristband is an annoying piece of junk; the cheap plastic stretches and tears, the computer unit doesn't fit well into its receptacle, and the very cheap clips DO NOT fit into the wristband, unless you artificially enlarge the holes.

    Loved being able to track my steps and activity wirelessly throughout the day with this little gadget. Had to return my first one after about 2 months because it stopped charging, geek squad replacement plan allowed me to exchange it. Now on my second one this year and it is also not charging, I will be returning it if I can and hopefully getting a different model.

    Bought it as a replacement. So liked it so much that it got bought twice. Also, Best Buy does price matching to Amazon. That's awesome.

    So disappointed

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Got my FitBit which I was so excited about... I was laying in bed while setting it all up and hadn't taken any steps with it yet. After looking at my steps as I'm still laying down, I had over 30 steps accounted for. I then put it to the test and came to find out just by me moving my arm it counts as a step. I'm highly dissatisfied and so disappointed and will be returning this item. I wouldn't recommend this to anyone.

    Disappointing product

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This was my sixth Fitbit. Even though I've lost one, had another get permanently stuck in the charger and ended the lives of several more by dropping them, I keep buying them because they push me to jog that extra mile. But the wristband is a loser from the get-go. It's really difficult to close and I don't have the patience to mess with it. So I'm returning it and buying a new Fitbit one WITH AN INSURANCE POLICY.
