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.
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.
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!
Beautiful watches! I loved mine so much, I ordered one for my son as well!
