love the midnight blue color
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I seem to be between sizes 14 and 13 though after thinking I would stick with 14 (used on middle finger then index at times) now might just do 13 even though it is a tad firm on the index finger at times. Was on sale but even more on sale after price match from Amazon before Prime day. I know Gen 5 is out though was taken by the midnight blue color and a bit of weight so the ring does not feel like a toy.

I Actually Came Back to the Ring 4
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been an Oura user for quite a while, and after upgrading to the newer version, I actually found myself coming back to the Ring 4, that alone should say a lot about how much I genuinely love this product. This ring has truly been one of the best investments I’ve made for my health and overall wellness. It has helped me better understand my body in ways I never expected!! From sleep quality and recovery to activity levels, stress, readiness and overall health trends. I love having real insights into how my body is doing instead of just guessing. What really sets Oura apart for me is that it feels like more than just a fitness tracker. The app genuinely helps guide you toward healthier habits and gives recommendations that feel personalized and helpful for everyday life. It’s become a part of my routine and has made me much more mindful of my health. If you care about your health, enjoy learning more about your body, or simply want to make smarter wellness decisions, I truly think this ring is worth the investment. It has been nothing but an amazing experience for me, and honestly, it’s changed my life for the better! ☺️☺️☺️

Awesome expierence!
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I was extremely pleased that Best Buy had the ring sizes and colors available so that I could make my decision quickly. I ordered the pink ceramic ring and received it in a couple of days. The process was seamless and I haven't taken the ring off since. I would definitely go back to Best Buy for all of my electronic purchases.

Must Purchase if Looking to Monitor Health
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been really impressed with the Oura Ring. It tracks my health in a very advanced and detailed way, especially sleep, recovery, and overall readiness. One of the best features is how accurately it can predict when I’m about to get sick. I often get early warnings before I even feel symptoms. It’s comfortable to wear, easy to use, and the insights feel genuinely useful rather than overwhelming. If you’re serious about understanding your health and catching issues early, this ring is absolutely worth it.

Oura Ring 4
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love everything that it tracks! I love that it tracks your sleep score, menstrual cycle, activities/workouts, stress, breathing, and your body’s temperature. I love that you can log your daily meals/snacks and get nutritional information from that as well. I haven’t found anything that I don’t like about it, it has been great overall! I wear it either on my pointer or middle finger.

Great!
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.upgrade was worth it! the only thing is that they say this ring is scratch resistant, which it is, but will still get blemishes. you need to contact oura to get a ceramic polishing pad which literally wipes away the blemishes. it does not come with it when you buy from best buy, but oura should provide it for free or you can get the polishing pad for cheap on amazon.
