    Stylish, Comfortable & Worth Every Penny

    I’ve been extremely happy with my Oura Ring 5. The sizing kit made it easy to find the perfect fit before ordering, and the ring is lightweight and comfortable enough to wear all day and night. The battery life has been excellent, and I love how detailed the health and sleep insights are. The app is easy to use, and the data has helped me better understand my recovery, activity, and overall wellness. The silver finish also looks sleek and matches everything I wear. If you’re looking for a smart ring that combines style with accurate health tracking, I highly recommend it.

    Best purchase!!!

    I honestly didn’t think I was going to love my Oura Ring as much as I do. I bought it because I wanted to learn more about my health, especially my sleep and recovery, but it’s become something I look forward to checking every single morning. My favorite part is seeing how my body responds to my daily habits. It’s so interesting to see how things like exercise, stress, eating late, or getting a good night’s sleep actually affect my readiness. It has made me much more aware of my overall health, and I find myself making better choices because I can actually see the difference. I also love that it’s a ring instead of a watch. It’s comfortable, lightweight, and I honestly forget I’m wearing it most of the time. The battery lasts a long time, and the app is super easy to understand without feeling overwhelming. As someone who has a heart condition, I’ve become much more intentional about taking care of myself. While I know the Oura Ring isn’t a medical device, it has helped me pay closer attention to my body’s patterns and encouraged me to build healthier habits. That peace of mind and daily awareness have been incredibly valuable to me. This has easily become one of my favorite pieces of technology that I’ve ever owned. If you’re thinking about getting one, I would absolutely recommend it. It’s more than just a smart ring. It’s something that motivates me every day to take better care of myself.

    Perfect Combination of Beauty and Technology!

    I absolutely love this ring! It has exceeded all of my expectations. My husband gave it to me for my birthday, and I was very happy. The new model looks so much better than the previous one. It is thinner, more elegant,and much more comfortable to wear. It doesn’t just look like a smart ring-it looks like a beautiful piece of jewelry. I chose the color that I like the most, and it is absolutely gorgeous. I receive compliments on it all the time. The ring tracks my sleep, heart rate, activity, and other health metrics very accurately. The app is easy to use,and the insights have helped me pay more attention to my heath and improve my daily habits.The battery life is excellent,and I barely notice that I’m wearing it because it is so lightweight and comfortable. It you’re thinking about buying the new Oura Ring, I highly recommend it. It combines beautiful design with excellent technology, and I couldn’t be happier with my purchase! The slimmer design is my favorite improvement over the previous generation. It feels more refined and feminine while keeping all the great features.

    Perfect for Tracking Sleep and Recovery

    I’ve been using the Oura Ring 5 every day, and it has exceeded my expectations. It’s lightweight, comfortable enough to wear all day and while sleeping, and the battery lasts several days. The sleep tracking is incredibly detailed, and I love seeing my readiness, recovery, activity, and stress insights each morning. The app is easy to understand and has helped me build healthier habits by paying more attention to my sleep and recovery. It also looks like a regular piece of jewelry, which is a huge plus compared to wearing a smartwatch all the time. If you’re looking for a smart ring that provides accurate health insights and motivates you to take better care of yourself, I highly recommend it!

    In LOVE with my Oura ring!

    I am absolutely in love with the Oura ring. The recent model has a nice slim design, battery last for almost a week. The tracking abilities of what you can monitor are amazing I was able to eliminate my period tracker by using this too. It’s a piece of mind on the finger couldn’t recommend this anymore, best purchase this year thus far! If I have any feedback, it would just be about the finish - I originally bought the brushed silver, and it almost had a blue undertone to it which I didn’t like and swapped it out for the silver, but the silver has more of a dark/gray look rather than a true bright silver ring. Still giving this five stars, but there is room for improvement on the color finish of the ring.

Questions & Answers
  • I have a oura ring 4 and i have the 2 year warranty. If i wanted to get the oura ring 5 since my oura ring 4 is scratched is there a way to exchange that or how does that work?

    It honestly depends on your bestbuy staff. Some may take it back and charge a restocking fee to return the item, and refund you. Others will only offer to give you the same ring at no cost since you are on a 2 year warranty. Technically it only covers the replacement of your Ring 4 with an identical ring 4 but it doesn’t hurt to try! Worst they can say is no.
