I'm pleased with my Gear 2. I really like how it looks. I have no buyer's remorse.
Battery life isn't an issue at all for me. The reason is, that I can't wear a watch to bed. My wrists have always puffed up a bit overnight. I'll go to sleep with the band fitting comfortably and wake up with it cutting in to my wrist. So, I always take my Gear 2 off and put it on the charger overnight.
The only two complaints I have are:
- The Bluetooth disconnects if I fold my arms together and completely cover the watch with my opposite forearm even though the phone is close by. This is my biggest annoyance because the watch beeps when it disconnects and then beeps again when it reconnects.
- The camera performance is pretty bad in low light or backlit situations.
