Ultrahuman Air Smart Smart Ring

Received product Did not work / turn on / charge No serial number or paperwork in box Unfortunately returned.

The ring size was not good. The battery did not last very long. Looking at online reviews, there were a lot of issues with build quality and battery life. Thankful for the excellent Costco policy on returns.

Excellent quality ring. I bought the sizing kit first to make sure I bought the correct size. It takes 2 weeks to fully calibrate based my daily routine and still shows helpful insights and body data during that time too. Easy to use and syncs well with Apple Health.

Tried 2 different rings, wouldn’t connect to iPhone, didn’t work. Got Oura ring instead, no regrets.

The gold colour started to come off after 5moutha & it wasn’t worn in water
