Beautiful watches! I loved mine so much, I ordered one for my son as well!
I just got this watch a couple weeks ago and am completely in love! Have already gotten so many compliments about the gorgeous color and style for a smart watch. I also think the YouQ app is so easy to use and insightful. I always suspected that I was a Morning Go-Getter but now my chronotype has been confirmed ;) I also love seeing my Power Score, and knowing the tech was designed in partnership with NASA. So cool!
I had one problem setting up the watch. It asked for a password when I was copying my Google Account to the watch, but my Google password would not work. It turned out it wanted my phone lock screen password, and I wasn't expecting this. Once I overcame that, the watch was excellent.
No problems. Connects to phone and wifi easily. Remember, you can use you phone to set the phone. Make sure you have password for the GMAIL account the watch defaults to. I have several gmail accounts. Get a second charger. I read all the bad reviews and I had no issues that they reported.
