I got my first smartwatch(Ticwatch Pro) in September. It works great with both my previous P2 and now P3. Once the update to OS happened late Oct, the watch became much better and less laggy.
Honestly, I think smartwatches are dumb. If I didnt work in an environment where Im not allowed to have my phone with me(sensitive data), I wouldnt have one. I just dont understand the need for one in any other circumstance if you always have your phone on you.
That being said, it does what I need it to do regarding notifying me of what I want to be notified of. Doesnt feel big on my wrist and the battery lasts very long. The stock strap felt comfortable but the watch wasnt heavy enough for me(Im used to much heavier solid watches), so I added a link style band and it feels perfect now.
