Love my Ring
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I love my oura ring. I wear it everyday. As someone who use to not wear rings, I was comfortable wearing it after 2 days. I always am scared it’s gonna slip but it never does even in water. I love the app, def a great buy! It can scratch up but I have it in gold and you can’t really see it. Plus you can buy ring covers on amazon

Best ring
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Honestly, I didn’t expect much, but this O-ring turned out to be really good. It fits perfectly and does exactly what it’s supposed to do—no leaks at all. The material feels strong and not cheap like some others I’ve tried before. Super easy to install, took just a minute. So far, it’s holding up great. Definitely a solid buy for the price. Would order again if needed.

Oura Ring 4
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great product so far. The battery life is amazing. I’ve compared it to my watch and it is almost perfectly synced. It’s lightweight and I forget I’m even wearing most of the time.

YES! Just buy it!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.LOVE LOVE LOVE! It is so worth the money. It is comfotable and light and you barely notice it after wearing it for a while. The one thing I will say is that you have to pay for the subscription to Oura but it is so worth it. The data you will get will change your day-to-day living and choices. Would definitely repurchase.

Compact Activity Tracker
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is a nice way to stealthily track your activities / sleep without needing something large on your wrist. It doesn't emit too much light, but there is some light you can see from under the ring, but it hasn't bothered my sleeping yet like my watch did.

Better than Expected
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I have been on the fence on whether to buy a smart ring or not and I’m glad I finally did. It helps immensely that, regardless of which OS your phone runs, the Oura Ring app both sync seamlessly with your phone’s native Health apps. It’s comfortable, light, durable, and the app has top-notch health insights and metrics (as a health IT specialist and informaticist myself, this is a massive positive for me). My only concern is the long term wear and tear of its coating/material but was able to grab some ring sleeves to lessen it especially when wearing it at the gym.

Amazing
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I had gotten myself an oura ring and when my husband saw mine he wanted one for himself so we went and got him one and he is absolutely obsessed! I use it for cycle tracking but my husband loves seeing his sleep patterns and calorie burn. We will definitely keep buying Oura rings as they continue to perfect they’re technology.

Oura Ring Review
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Oura Ring feels effortless — light, simple, and easy to forget you’re even wearing it. It quietly tracks your sleep, stress, and daily rhythm without any screens or noise, just clean insights that actually help you understand your body better. The battery lasts almost a week, the app is clear and friendly, and the whole experience feels more like a wellness companion than a gadget.
