  • Great Ring Features But Not A Great Finish

    Great features but the finish goes bad really quick. My wife and I have had ours for less than two months and after taking care of them as much as possible they’ve still gotten pretty scuffed up. I have the silver finish and it’s nowhere near as bad as my wife’s gold finish ring. Considering hers was way more expensive and looks worse than mine, I wouldn’t consider the gold one a great deal.

    Like the ring and the way it fits. The app is cool to know heart rate stress and other features. Don’t like that they charge a monthly fee for it after paying for the ring.

    It doesn’t pick up workout sessions as well as the Apple Watch, that seems to be the only thing that’s holding it back from being perfect

    I absolutely love my Oura ring. The only reason I won’t give it 5 starts is the battery.it was advertised as 8 days but I get 5 if lucky and it’s really frustrating when traveling.
