What reviewers say about the Oura Ring 4
Two whitelisted hands-on testers (TechRadar, Engadget) call the Oura Ring 4 the best smart ring, praising comfort, sleep tracking and the redesigned app. Both flag the mandatory $5.99/month subscription that paywalls essential features. In real-world use, TechRadar drained a Size 10 ring in about five and a half days of constant use with workouts, while Engadget regularly got seven days on the same size over two months of lighter use. (Numeric measured values were dropped because the digit forms did not literally appear in the source text; the battery claims survive within verbatim quotes.)

I drained its battery down, which for my Size 10 ring took five and a half days of constant use, including several workouts.
Sleep tracking was highly accurate: Oura boasts some of the best sleep tracking in the business, said to be comparable to a professional polysomnography machine, and it didn't disappoint.
the ongoing subscription brings down its prospect as a good-value package.
I wear a size 10 ring and over the last two months I've fairly regularly wrung seven days out of the device before I'm advised to find a charger.
Oura's latest Ring is the best smart ring on the market. But its range of functions remains limited by its size and the fact that it's a ring.
the system will frequently assume you're exercising when it sees movement plus an elevated heart rate. It'll often accuse me of doing some form of rigorous workout when, in reality, I'm just going up and down stairs while I get my kids ready for school.
