Highly recommend for you swimmers!!! Of course for runners too!
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.

Tiny, rugged, basic, and excellent!
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.

Numerous defects: sealant leaking out of seam, and refusal to sync/connect
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.

Reviewing after around 10 days of use Pros: Excellent tracking - Fitbit's algorithms are very accurate at tracking the distances and exercises even without having a GPS sensor built in Excellent app - love the infographics shown. it is one thing being able to track steps and another representing it beautifully in all the myriad ways that they do Very lightweight - get used to wearing it in just a few hours Swim-proof - have yet to go for a swim but was one of the major reasons for me buying it Cons: Battery - this is the biggest let down. for a device which doesn't have GPS or a screen, the 4-5 day battery life is a major let-down. The compact, lightweight form factor only partially makes up for this No clock - call me a tradionalist, but if I'm wearing something on my wrist, it should bloody well show the time No heart-rate monitor, GPS - while Fitbit's algorithms do a great job of calculating calories and distances, it is always good to have dedicated monitors for these. but then, this is the cheapest of the Fitbits

Me agrado bastante esta banda. Dudaba en adquirirla debido a que no tiene pantalla. Pero a favor tiene que es demasiado delgada y discreta y es a prueba de agua. La pantalla no la extranie ya que toda la informacion esta disponible en el celular mediante bluetooth.

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.
