    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.

    Amazing BUT.,.

    The new oura ring is amazing, I’ve had it over a week and it hasn’t scratched, only charged it once, and looks amazing. HOWEVER, it has no weight to it, its so thin it’s impossible to believe there’s something things inside. If you have and apple watch a garmin, a fitness tracker ring, GET THIS INSTEAD!

    Oura Ring/Gen 5 IS worth a close look.

    I have been wearing Oura’s rings since Gen 2. The integration between the ring and its app is truly refined and polished. The feature set has expanded quite a lot and it is easy to understand why Oura is the one to beat. Ring 5 vs. Ring 4: worth it? If you are a ‘casual user’ who only checks the data every few days or so—maybe not. If you are a regular user who faithfully checks the Sleep Metric as I do each and every morning, I’m thinking yes, you may very well appreciate the refinements from gen 4 to gen 5. Gen 5 IS remarkably smaller and lighter than Gen 4 and I noticed it immediately. It is a lot less bulky and barely protrudes where Gen 4 would regularly rub against my adjacent finger. Battery life so far is noticeably better. Gen 5 seems to use about 11 percent of the battery each day (plus or minus depending on my activity level). Gen 4 was in need of a battery boost about every four days. So far Gen 5 is getting me about 8 days or so. The real value with any fitness device comes in how helpful (and how accurate) the software proves to be. With Oura, I can easily cross check against Apple Health (I own an Apple Watch) and I find that Oura’s metrics tend to more closely align with how I am actually feeling. It does a great job too of warning against looming fatigue from too many hard gym workouts, for example. And it will offer useful advice or guidance on how to re-set, maybe take a day off,etc. This combined with the comprehensive Sleep Metrics really does provide me with personal, useful, and accurate health and lifestyle support. And the fact that it is a simple (looking) and very attractive ring without a display, no speaker, no buzzing, no intrusions(!), makes it that much easier to always wear it. I’m a bit of a health nut, health data geek and I can easily say this is my favorite health tech device. Last point—updating the ring in the app truly could not be easier to do! I had the old ring disconnected and the new ring recognized and synched in under 5 minutes. Absolutely a refined, polished ownership experience.

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.

  • I put on the sizer and it felt good but my fingers swell during the nite. Should I stay with the size that feels right during the day?

    I would wear the sizer over night to make sure it’s comfortable and safe to remove the next morning. Last thing you want is to purchase it, it get stuck and then have to cut it off!

    No

    Answered by SHANNONM
  • Is there a subscription required and how much

    yes at $6 a month but it's so worth it. I've had an oura ring since 2024 and the app is very impressive. It tells you things you won't believe. go to the website at ouraring.com and you can see all that the app will tell you with the subscription. You can also pay by the year and I think you get a discount.
