I switched from Oura 3 and I am very happy. Apart from the fact that the price is quite high, the ring has no drawbacks. I find the material more durable and the measurement more accurate. Beautiful design, luxurious packaging, seamless introduction to the app. Recognises activity well.

It tracks a lot of useful health data, and the sleep tracking is especially accurate and reliable
I also really like the design, app, and premium packaging
The battery life gets worse over time (1-2 months)
The ring scratches very easily no matter how careful you are. I expected much better material quality.

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.

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.
