I like it. Nice enough that I didn't have any interest in upgrading when the newer ones came out. I started with the OG G Watch and upgraded to the Urbane at full-price. I don't regret the move. I don't really care for the watch to have it's own mobile data (and to pay extra each month for it). Other than that and a speaker, which I'm also not convinced that I'd really use much, I don't know that any other watch has anything more at this point in the game.
I wore mine all day yesterday and simply turned it off at the end of the day. Still at 44% after turning it back on this morning before work.
If you have any specific questions, I'm happy to do my best to answer them.
