I have tried other cheaper smart watches -- only to be disgusted with them. This watch is very dependable. A charge can last days. I spent two days at a friend's house and forgot my charger, and it was still running when I got home. As for the health functions like blood pressure and pulse, I find them to be fairly accurate. It's not as good as what a doctor would have, but it's close enough. As for looks, I have had many compliments on it, and it id extremely comfortable to wear. I highly recommend it. . .
