all measurements
it gets scratched during normal wear (for a ring for normal wear, I don't recommend it) so that it doesn't get scratched, then one wouldn't be able to do anything
is quite massive

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

Big disappointment so far - technical error during activation We bought the Oura Ring Gen 4 for my husband, but right at the first start-up we encountered an error that makes it impossible to complete the setup. After you pair your ring and log into the app, it will redirect you to a website where you have to choose a subscription. However, the page crashes with an error and only a technical message about an error in localization (missing price and payment date) is displayed. We tried everything possible - a different browser, incognito mode, disabling VPN, switching the phone to English, reinstalling the app. Nothing helped. Support has not yet advised. It's possible that it's just a temporary bug, but for a device costing several thousand crowns I would expect a smooth commissioning. I recommend waiting to buy until Oura fixes the bug with the Czech version of the settings.
unable to start despite activation error

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

When I buy the best product on the market, I expect to at least register it. Officially there is no mention of the bug, support is not responding. I would expect at least an official statement on the problem and when it will be resolved. Really disappointing.

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

A completely unique product for measuring sleep, stress and activity.
The charts are clear and very nice processing of the application and the environment.
Physically, the ring is black. nice, lightweight, no hang-ups.
The battery lasts about 8 days, and eventually reports a message to charge.
nothing, I don't mind the subscription, it's just an investment in the company and its improvement.
The review that you can't add food and drink to the app is nonsense, that's not what the ring is for. that's what the calorie charts are for, for Christ's sake, sir.
