I have LG G Watch. I've been very happy with mine. The interface is quick, the battery lasts a couple days with regular use, and it's running the same level chipset as pretty much all the other Android Wear devices. I actually like the simple form factor and rubberized strap, especially for fitness stuff. The square display does better than circular ones at displaying certain types of information, and is pretty readable in everything but direct sunlight. The lack of Wifi support sucks. I'd also love an integrated heartrate monitor, but by most accounts the ones on other Android Wear devices suck. So all in all, I'm happy sticking with this little guy for a while. I got mine for $80 several months ago, and $50 is a great price, even as a refurb.
