I have had an LG Urbane for almost a year. It was a gift from my wife and kids for my birthday. I don't think I ever would have purchased a smart watch on my own but I have really enjoyed it. I have a lot on my work schedule and the notifications are very handy. The directions on my wrist are appreciated especially when walking so I don't have to stare at my phone and look lost. I find it handy to leave my phone on my desk and not have to carry it to get notifications. In general, as someone else said, the extra source of notifications is very useful. There are other applications but personally I didn't invest much effort after I realized I couldn't reliably press the tiny buttons on the calculator applications.
When other people see it light up for a notification, I often get the "is it an iWatch" question. I politely explain that Apple isn't the only company that makes smart watches. The LG Urbane is a round faced watch which actually looks like a nice men's watch. It isn't gimmicky looking. It feels comparable in weight to the Seiko Titanium watch it replaced. It will last about 36 hours on a charge for me but I charge it every night. I show them the features and they usually come away impressed.
If you want a status symbol or expect a magical capability, then you will be disappointed. At Apple prices, a smart watch is a very questionable purchase. But the feature/price ratio is better on the Android side. Plus you have more choice on style.
