Since I pre-ordered the Galaxy Note 7 thru Best Buy, I received the Gear Fit2 as a free gift. After using the watch for a couple of days, here a few thoughts on it... The watch is very nice in design from the watch band which is easy to put one (the band on one end slides thru the end of the band on the other side and then hooks into the band holes - much like that of the Apple watch). I have not done any extreme exercise, but the band has stayed snapped in place with no issues (I think even if it came loose, it would take it some effort for it to fall off as it would have to pass thru the loop). The bands are removable but I have not looked at replacement options. The Fit2 is currently paired with my Moto Z Force and it uses the same app as Samsung's other watches - although I did have to download and install the Gear Fit2 Plug-in from the Play Store. There are several pre-installed watch faces that are designed to give you necessary fitness info - which is quite nice. While this would not be considered a "smart" watch, it does allow notifications from the phone to the watch and you are able to select what notifications you wish to receive. I use the Verizon Messages app which I cannot reply from the watch but with the gMail notifications, you can reply with "canned text replies". You can download additional watchfaces and apps thru the Galaxy App store, although the selection is not as diverse as it is with the Gear SmartWatches - which is no surprise as this is a fitness watch. The watch seems to accurately track my "steps" and I really like that it counts "stairs or floors". I do not feel that the calorie burning is that accurate as it shows activity upon taking it off the charger while everything is reset to "0", it is at 500+. It comes with a dock style charger, charges fairly fast and the battery life has been fairly solid in the couple of days that I have used it. Again, I am not a runner so I have not used it running and cannot comment on the use of GPS and if that affects battery life (my guess would be that it certainly could). The watch fits nicely on my wrist, I like the elongated screen and it is easy to read (inside and out). So far, no real downsides for me but that could change with more use. I am pretty sure that @YankInDaSouth has one of these and can probably provide much more insight. I did not try the first model of the Fit as @mountainbikermark has, but the watch is pretty solid and I would think it has great potential providing you with both fitness tracking info and phone notifications as needed / wanted.
