Yes. I bought an LG G Watch for super cheap so I don't necessarily regret the purchase but I don't wear the watch anymore.

1. It's annoying to charge it every single day. I didn't think it would be annoying but having to take the watch off my wrist and plug it in every single night was annoying.
2. It's not waterproof or dust proof enough to not care about where I go.
3. It's bulky. Even if I didn't have to take it off to charge it I wouldn't want to sleep with it on. It's much larger and heavier than most watches I've worn.
4. Android Wear is buggy. There was a point where I wanted to use Google Fit but the step count wasn't accurate so I wanted to use the step counter from the watch. Nay. Pick one. I was more interested in the step counter so I just ditched Google Fit and gave up all the other benefits. Frustrating.
5. It would not play well with other bluetooth devices such as my car and speakers.

But most importantly is that it got in the way of the rest of my life. Putting my phone on silent means it's out of site and out of mind. With the watch I needed to basically take it off or put it on airplane mode. Just putting it on silent doesn't solve the problem of seeing all the notifications come to my wrist and distract me. It was annoying to have to make sure the watch wasn't going to blow up while I was out to dinner with my wife and I don't care who or what is trying to contact me. I found more often than not that instead of focusing on what was happening in the actual world around me I was fiddling with my watch or swiping away notifications that I otherwise would have just waited on.

There were a lot of great things, too. I loved having GPS directions on my wrist, vibrating on turns, etc. I loved being able to set timers and alarms, quickly respond to messages, filter emails, etc. Those were all great. They just didn't overcome the inherent problems with having a connected device on your wrist.

Just my two cents but I personally would not buy another one almost regardless of the improvements to Android Wear.
