    My wife and i both bought one. It gives a lot of information and metrics. If you act on the information then it seems to be beneficial. I have improved my heart age by half a year already. It is noticeable with some activities like driving.

    I purchased the Oura - Ring 4 - Smart Ring for my wife as an adjunct tool to monitor her cardiac rhythm. She wore a Holter Monitor prescribed by her physician for 2 weeks, and I also purchased an Apple Watch Ultra for her to monitor her cardiac rhythm. The Ring 4 is the easiest to wear, charge, and monitor via its app. As her husband physician it was the simplest device to track for her. Now that she no longer needs it, I wear the ring on a different finger, and I enjoy the physiologic insights it gives me about my body.

    This is a great, comfortable and comprehensive passive fitness tracker. If I could wear an Apple Watch, or any smart watch, I would pick one over this, due to functionality, however, due to limitations and tattooed skin, this fitness ring is the next best thing
