Important information
Directions
Keep it Clean: Regularly clean your band and wrist—especially after working out or sweating. Rinse the band with water or wipe it with a small amount of rubbing alcohol. Do NOT use hand soap, body soap, dish soap, hand sanitizers, cleaning wipes or household cleaners which could get trapped beneath the band and irritate skin. Always dry the band well before putting it back on. Keep it Dry: While Fitbit devices are water resistant*, it’s not good for your skin to wear a wet band for long periods of time. If your elastomer band gets wet—like after sweating or showering—rinse and dry it thoroughly before putting it back on your wrist. Be sure your skin is dry before you put your band back on. Don’t Wear It Too Tight: Make sure your band isn’t too tight. Wear the band loosely enough that it can move back and forth on your wrist. If you use Fitbit products with Purepulse Heart Rate tracking, for better heart rate readings during exercise, we suggest wearing the band so it’s secure, but not too tight, and wearing the band higher on your wrist (about 2-3 finger widths above your wrist bone). Lower the band on your wrist and loosen it after exercise. Give Your Wrist a Rest: Prolonged rubbing and pressure may irritate the skin, so give your wrist a break by removing the band for an hour after extended wear.

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.
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.
However, one of the biggest downsides is that it loses track of time rapidly if you don't constantly sync it - a silent alarm set for 6am may go off anytime between 5:30 and 6:30, which is incredibly frustrating. It's also cumbersome to set this alarm and there cannot be multiple. The pebble also requires location services to be on to sync, but this isn't necessarily a fault of Fitbit, but it is why mine isn't constantly syncing.
It also is potentially inaccurate. Despite me and my wife wearing a matching set of these on the same wrist, walks we take will measure significantly differently. When walking with someone with an Apple Watch (which uses GPS), a walk around town side by side resulted in a massive 2 mile claimed difference between my Fitbit and their watch.
All in all, it's a nice and simple reminder for healthier living, and the app is what's useful. But all in all I'm rather skeptical of it's measurement methods.

アプリのバージョンアップで不具合がある時がたまにあるので、基本的にアプリのバージョンアップはすぐせず、評価者の意見を聞いてから遅れてする、もしくはしないようにしています。私個人的には、買って満足しています。
