Bought for my wife to try. Total wears for two weeks, the flight is normal. I swam in them in the sea, dived and swam, everything is fine. She sleeps in them, they do not interfere with her and do not crush. The screen is very juicy. The charge is kept for more than a week + - a couple of days maybe. Depends on the time of use. All in all, this is a great watch for the money. Different pros: Not big. Comfortable. Waterproof. Soft strap. Bright and clear screen. Duration of work without charging. Functionality for the money. Different cons: No ECG, but I don't really see that as a disadvantage. It's more like a wishlist.
