In terms of functionality, the ring is truly unsurpassed.
It monitors health much better than a smartwatch.
Pairing is easy, the ring lasts a few days on a charge (on the manufacturer's recommendation I charge continuously and not to full).
It fits perfectly, I more or less don't even know about it.
I strongly advise against buying the matte version. After a few days, the ring was already badly scratched in several places. With the price of the ring, I would expect the color to be more durable (plus it's at a premium). I'm going to complain

Recommends trying on the size in advance using a sizing kit
Highly accurate monitoring of sleep and its phases
recognizes and records activity well
decent battery life (about 5 days)
overview app (for a fee)
the matte surface is easily scratched, especially during outdoor activities. Already after a week there are visible scratches on it.
In the water, I'm worried that he might get out more easily

A person buys a premium product for quite a large amount, accepting the subscription obligation in the app, and yet cannot use it because a subscription cannot be created. Support alone won't help - the automated assistant will advise you on things you can read in the help. But one will not know the real solution. I'll try a few more times and otherwise return.
Quality workmanship
Fast delivery
Cannot create a membership in the app

Hello, thank you for your review. We are very sorry for the complications with the registration of the Oura Ring. We have addressed the issue extensively with the manufacturer and as an apology, the manufacturer will provide 3 months of subscription to customers who have purchased a smart ring from us during this time. At the moment everything should be working fine. If necessary, please do not hesitate to contact us. Thank you and have a nice day, Ondřej - Alza expert
