Flex 2, Black (US Version), 1 Count

This summer my fiance requested a Fitbit. One night there was a sale too good to pass up, so I quickly did as much research as I could and weighed it with what my fiance wanted in a fitness band. I got her the Alta back in late June and she loved it! After having it for a week or two and really getting acquainted with it, she started showing me all the stuff it tracked in the app and I was seriously impressed. As a longtime Samsung Gear Fit user, I saw the Fitbit app blew the Gear Fit's out of the water. When I originally got my Gear Fit I wanted something that tracked my heart rate and steps but also could show me time, texts, and notifications from certain apps, as I missed wearing an actual watch, but wanted some tech too. While I still wanted a watch, I decided to get myself the smallest, cheapest Fitbit so I too could utilize the app, and I am thrilled with this little guy. So these days I still wear my Gear Fit on my watch arm and the Flex 2 on my other wrist. It works for me and I am very happy. The thing I love about the Flex 2 is its size. It is so small! My one main problem with the Gear Fit was that it was just a bit too big to sleep with on, as it would cause my arm to really fall asleep badly, so I could never utilize the sleep function of the watch. Even the Alta my fiance has is too big for her (causes the same problem on her as my Samsung does with me) but this Flex 2 poses no such problem with me, so I have been really happy that I can now track my sleep. It has given me some serious insight into how I spend my sleeping hours. Overall, I lover this thing! The app is superb, the Fitbit is tiny, water resistant, and holds a good charge. The band is nice too. The next smartwatch I get will be more aesthetically pleasing and less fitness based because I've got this little Flex 2 that tracks all the fitness type stuff I need.

Ok, I am a longtime Fitbit user and was hoping the Fitbit2 would be a quantum improvement on an otherwise great product. After using it for a few weeks I can say that it certainly is. The core functions of the original Fitbit always served my running workout routine well. However I always wished I could use it in the pool. That said I was skeptical it would actually record my lap swim accurately. It worked great, better than hoped for. My first clue that this was a quantum improvement came after the first gym visit wearing the Fitbit2. It recognized that I was on a elliptical machine and recorded it promptly. For the swim, I set the pool length (finding how to do that was not easy though) and started in. I also set it to notify me when I passed my 45 minute first benchmark. I also used a watch and counter also to make things honest. At 45 minutes the band vibrated which I could feel in the water. After I found it had not only correctly timed the 1 hour swim, but had correctly calculated the distance and added to the Dashboard!! Wow, just what I needed!! I noticed a few concerns, but nothing that have kept me from being impressed. All and all, so far HIGHLY recommend. Pros: 1. Does all the original Fitbit did in a smaller more secure package 2. GREAT for swimming laps. No need to wear a separate swimming watch. 3. Update process was smooth 4. Better appearance and stronger clasp. Cons: 1. Seems to last about 5 days between charges, old one was 7. That may change as I stabilize my usage pattern. 2. Not simple to program swim mode. Seems simple after you figure it out but not immediately intuitive. 3. The way the device inserts into the band requires bending the band. This concerns me that band breakage such as with the Fitbit1 may become a problem again.

I have been using this tracker for about a month thus far and wanted to provide a bit of information as I find these detailed reviews useful, especially from folks who have been using the product for awhile. I had previously had several iterations of the Jawbone UP band (UP24, UP2), where I had numerous issues with the band falling apart. I had been waiting for the Flex 2 to come out as I wanted a smaller tracker with an interchangeable band (so if the band broke, I need not replace the entire tracker). After using this product for several weeks, I would say I am definitely happy with it. Will go through a few Pros and Cons. Pros: 1) Band is definitely durable (the tracker actually comes with two different sized bands). Rubber feels like what you would typically see on a watch band and it does not feel flimsy at all. 2) The iPhone app is nice and easy to navigate. There are lots of features such as weight and food tracking (that I don't use) and these are probably useful for some. 3) Tracker syncing to the iPhone app is seamless. Setting it up was easy. 4) Tracks steps in real-time. If you watch the app and take some steps, you can actually see your step count tick up. 5) Text/phone call notifications are a definite plus and help me catch those missed texts that get me in trouble with the misses. 6) Band is waterPROOF. I have not swam with this band yet but I have showered with it with no ill effects. Cons: 1) I am finding that I need to charge the tracker every 4-5 days. It is nice that the app sends an e-mail when the battery is running low, however I was able to get 1-2 weeks of battery on the old Jawbone Up products. 2) While the band is durable, it is rather difficult to get on and off. I feel that the degree of prying to release the band is eventually going to damage the band itself eventually. Not sure: 1) Compared with the Jawbone UP, I am finding my step count to be somewhere around 1000 to 2000 higher per day. Not sure if this means that the UP was under counting or the Flex 2 was over counting, but worth mentioning. Overall I give it 4 to 4.5 out of 5 stars and would definitely recommend it as a mid-range tracker at the present $99 price point.

UPDATE: 1 DEC 2016 I've gone through 2 Flex 2's already. One had glue or some sealant coming out of the seam of the casing. The latest one refuses to sync to my phone after the double-tap procedure. After doing a search online, it seems this is a hardware defect and has to be replaced. After having 5 Charge HR's fail, a Fitbit One fail, and a Fitbit Flex fail.... I'm officially giving up on Fitbit. The step count is also very inconsistent. Original Review: I've owned and used a variety of Fitbit products: Zip, One, Flex, and the Charge HR, as well as other fitness trackers like the Garmin Vivosmart HR, Vivoactive HR, Vivomove, and GPS fitness trackers like the Forerunner 101/305/901XT, Magellan, MotoACTV, Epson, and Timex. Where Fitbit wins over the competition is in its popularity and social accessibility. Other than that, there's no other advantage to Fitbit. I love my Garmin Vivoactive HR as it does everything the Fitbits do as well as the GPS trackers like the Forerunner. I took my Vivoactive HR through the Warrior Dash and it survived swimming, mud, shock/vibration, and being slammed against obstacles. The Forerunner 910XT works better for me on a bicycle due to having a mount for the handlebar. The other GPS trackers have either died on me due to extreme cold weather running or just performed poorly. I went through 5 (that's right, five) Charge HR units through warranty before Fitbit finally denied my warranty claims. They all failed with sweat/oil intrusion, sluggish syncing, and a battery life of 5 minutes. I tried numerous things: not charging them until it was necessary, charging them every night, taking them off when washing my hands, not working on my car with the Fitbit on my wrist, etc... short of keeping them unused in a box. They all failed and died. Judging by the number of comments on my 1-star Amazon review of the Charge HR, this was a COMMON problem. The Flex 2 claims to be water proof / swimproof, much like the Vivoactive HR and Forerunner 910XT (as well as any other Garmin GPS tracker), and seems to be the ONLY Fitbit product that is swimproof. I'm not sure why Fitbit didn't just make all of their products swimproof or waterproof to 5 ATM because it is idiotic not to do so on a daily-wear fitness tracker (that is exposed to sweat, rain, showers, etc...) The Flex 2 is noticeably slimmer and lighter than the original Flex. I like how they made the seal tighter for the tracker unit, but water still gets trapped in the band. The new clasp is also made better as there are lips to keep the metal clasps engaged with the band, and it is a tighter clip as well. Trying to remove the band is always a chore, so it doesn't come off accidentally as easily as the original Flex. There are no displays other than a series of LEDs, and I'm perfectly fine with that. After having used the Zip, One, Flex, and Charge HR, I can guarantee that you will not miss having a screen because you can see so much more via the app. I use my Garmin Vivoactive HR as a daily wear watch/fitness tracker/GPS trainer because that screen tells you time, and the Connect IQ apps have useful tools like a digital compass, AccuWeather minutecast, Accuweather forecasts, and some apps created by others like a Vo2Max app or a Triathlon mode app. Don't expect any of that from even the best Fitbit unit, so I don't really care if there is a screen on the Flex 2. The Flex 2 is small enough to wear on the same wrist as your dress watch, so it is a moot point. The Flex 2's step count is about the same as that of the Charge HR. The Garmin Vivoactive HR is really conservative on its step count and its floor count is practically worthless. I'd say the Vivoactive HR counts about 4000-5000 steps less per day than the Charge HR. Based on current testing, the Flex 2's step count is about the same as the Charge HR. Everything is cool except the clasp is a bit tight to remove, I'm expecting the band to break due to how tight the clasp is. Water still gets into the band, necessitating periodic cleanings to prevent mold/bacteria development. Durability awaits to be seen. Every single one of my old Fitbits (all 8 of them) are dead from sweat/oil intrusion, battery failure, and connectivity failure. I have a graveyard of dead Fitbits in my office. I will definitely keep my review updated as time goes on, because I am still not sold on Fitbits being durable enough to handle my fitness routines.

This was my first Fitbit device, and I am very pleased with its performance. I had debated getting the Flex 2 or the Alta, but chose the Flex 2 for its slim profile, waterproof design, and lower price point. I have yet to incur water damage, and the five-light design is very minimalist yet informative. One of the main reasons for purchasing a Fitbit was for the silent alarms, as my alarm would annoy both my roommate and me in the mornings. Although I at first set backup alarms on my phone, I turned them off as I realized the Flex 2 had very strong vibrations that have never failed to wake me up in nearly a month's use. A common complaint is the press-on design of the band, and at first, I was disappointed at how difficult it was to put this on. However, after use, it became much more comfortable to put it on, but not to the point where I felt it was in danger of falling off by itself. Finally, I love the Fitbit software, whether online or on mobile. I like the social aspect, particularly the friendly competitions and challenges. Although this model lacks a heart rate monitor, I use my Samsung Galaxy S7's heart rate sensor in conjunction with my fitbit to track my exercise statistics. PROS: Slim and minimalist design Durable band Waterproof pebble Strong, effective vibrations (alarms, notifications) Software CONS: no HR monitor (not truly a con at this price point) I did not receive any compensation for this review.

It's interesting that I'm writing this review a year and a half after I bought this item... and it's now broken and unusable. I bought it around September 2017, loved it instantly for the sleep and exercise tracking, and it provided significant great feedback to me. Around April 2018, I lost all the data when the app rebooted or was updated or something. I tried calling Fitbit and they had no good answers for me - the data was just gone. I tried to get over that and continued happily using the product. Regarding accuracy: it sometimes thought I was sleeping while I was meditating or at a movie. In the fall of 2018, my watch of 10 years died and I contemplated getting a watch/tracker. On the advice of a friend, I got the Amazebip ... but didn't like it right away and returned it. This episode showed me that Fitbit was a superior product and I appreciated the quality generally speaking. I contemplated buying the Fitbit Versa although: 1) the price was too high at $200 and 2) I had some lingering mistrust about all the lost data... Six months later, I haven't bought a watch yet (incredibly it's now been almost a year since I wore one) and then... March 2 (2019) my Fitbit broke. It fell off my wrist and I didn't understand why - then I saw that one of the pins had broken and on top of that, some of the holes had enlarged and didn't hold the remaining pin anymore. So it's now sitting on my counter as a dead tracker device and I have no tracker....

I had the last flex and hated it. I returned it after trying to like it for 2 weeks and still hating it. I'm really not a fan of wearing anything on my wrists at all and I have small wrists and a wrist bone that sticks out...and no matter the band on the last flex it irritated my wrist, it was clunky, and unattractive. I really wanted a Fitbit and to like them since most of my friends and family have one, but all the ones they kept coming out with were just bigger, clunkier, and uglier. After seeing this new one in stores I got excited and ordered it, but was very very skeptical. I am still in shock at how much I LOVE this thing! It is SO small and lightweight and even when I use the wristband I can hardly tell I have it on. I actually wore it on the band yesterday and panicked a couple times thinking it had come off and I lost it because I couldn't feel it in my wrist, but nope. It was still there. I also LOVE that I can wear it on a clip! I bought the high-rated, off-brand, magnetic clip on here and use that most of the time clipped over my bra strap. I constantly forget I have it on. This thing is also DEAD ON ACCURATE, unlike the old flex I had. No matter how I calibrated my old flex it was off by like 30 steps in 100. This one is dead on, even when I wear it as a clip! I also thought it might bother me not being able to see actual steps on a readout, but every light is a quarter of your goal and it's easy to see. Plus, I usually just check my app for my steps anyway. Overall, I am one VERY happy customer and Fitbit has won back an unsatisfied customer! It's tiny, lightweight, accurate, waterproof, and you can wear it on a clip of in a pendant and not just on your wrist. What's not to love?!

I've owned several Fitbit devices with the HR feature, but I decided to buy an Apple Watch so I didn't need them anymore. So I thought..after only a week I really missed the Fitbit features and decided on the flex 2 so I could wear it on the same wrist as my watch. The lights will light when you reach so many steps throughout the day. You can also get phone and text notifications. I don't use those features so I have those 2 turned off. I use the alarm feature to wake me up in the am and to remind me it's time to clock in at work. It tracks sleep...I honestly don't think any of them are very good at sleep tracking..but that's my opinion. I love the fact that it's waterproof and I can wear it in the shower. I never take it off but to charge it. All of the other Fitbits I owned (charge Hr and the blaze) the bands gave me a rash and I had to take them off frequently. The flex 2 hasn't done that yet. Not sure if it's because of the thinner band or why. I love how thin the band is. I don't have a problem putting it on or taking it off. I ordered a 3 pack of different color bands directly from their website to change them out. Overall..if you don't need the hr feature, stairs climbed and don't need to know the exact count of your steps without looking on the app this is a great option.

Produto excelente, bonito, leve e ótimo para o dia a dia... O único defeito é que não notifica mensagens de texto do WhatsApp!

سوار حلو ويجي مقاسين داخل الكرتون ويقرا الخطوات والتمارين عن طريق التطبيق وتنبيه بالمكالمات والرسائل عن طريق الاهتزاز شكرا على المنتج

Buen producto, su precision en pasos y sueño es excelente, ademas que detecta el ejercicio aerobico que hago. la bateria me dura una semana aproximadamente

Delivered on time, works well and as described. It’s very minimal and seems durable, just what I wanted that I could wear all the time , even to bed.

This little gizmo that will tell you to move when you're being lazy, and celebrates when you hit your step goal! It's simple, it doesn't have a watch because time is a silly wibbly wobbly ball of...stuff anyway, I like it. This is a lot of fun and has helped keep me from dying early from a sedentary lifestyle as a human battery powering the Matrix.
