It's very good for the price, the only thing to keep in mind is that the battery lasts a couple of days.

Itis nice but there are no instructions how to operate to take photos

Pros. the heart rate sensor is fantastic and the time. (can't really mess that up) cons.for some reason there seems to be missing half my sleep time (it's always showing around 3 hours instead of six) compared to my smartwatch and the steps at the end of the day always about 2500-3000 steps less compared to mine oneplus watch 3 but for 20 bucks it is what it is.

Product delivered faster than expected (6 days sooner). Charged quickly and easily connected to the phone.

The ring doesn't work. The time doesn't show. I've unbinded it and re bonded it several times but it only shows numbers which increase each time i tap it. Example - i tap it and it may show 4 and then tap it again and it shows 6 and keeps going up each time. I want a refund
