    • Amazing upgrade for oura Amazing upgrade for oura
Style: Ring Size: 10 Color: Black
Review Image by Mason Schutt
Love this item! It is super durable and fit perfectly, the battery is lasting roughly 9-10 days on my size 10. It looks as described and it’s so small I can barely tell it’s there most the time! Super comfortable.

    • ★★★★★ Unbelievably comfortable and finally practical for the gym!
Style: Ring Size: 8 Color: Black
Oura completely knocked it out of the park with the Ring 5. I have been looking for comprehensive health tracking that doesn't feel obtrusive, and this miniaturized design is exactly what was needed. Here is why I highly recommend the size 8 Black model: Barely-There Comfort: They aren't kidding about it being the "world's smallest." At 40% slimmer than previous generations, it makes a massive difference in daily wear. I can actually wear it comfortably while weightlifting without it digging into my fingers or throwing off my grip. Incredible Durability: The black titanium finish is sleek, and the upgraded PVD coating is surprisingly tough. Despite heavy daily wear and regular gym sessions, it has held up flawlessly without picking up frustrating scratches. Pinpoint Accuracy: The new 12-pathway sensors are incredibly precise. Whether it is tracking my heart rate on the treadmill or breaking down my overnight sleep stages and daily stress levels, the data is consistent and genuinely useful for optimizing recovery. Set-It-and-Forget-It Battery: Getting 6 to 9 days of battery life out of something this tiny is fantastic. It charges quickly, meaning I never have to worry about missing overnight sleep data because it died on my finger. If you want precise health and recovery insights without the distraction of a bulky wrist wearable, this is hands-down the best device available. The smaller form factor is an absolute game-changer! ... show more

    • Love it!
Style: Ring Size: 13 Color: Black
Absolutely love this device. I am coming from iWatch and the ring is so much more convinent in terms of size, battery live and comfort. I used to wear iWatch to monitor my sleep, but with the ring it's so much less annoying :) Software is well designed and useful. I agree the V4 sizes made more sense, but my size 13 fits on one of my fingers and I am ok with that. Great product ... show more

    • Super thin and light!
Style: Ring Size: 9 Color: Black
I’ve been wearing it every day since release and so far so good! I can’t speak to the longevity or battery life just yet, but will come back to update after a few months. As far as first impression, the ring is significantly smaller! I wear a thin Enso silicone wedding band and it’s barely wider than that. I went with black and it looks great. As far as sizing, I wore a 9 in the gen 4 and it was slightly big. I was one who would have benefited from half sizes. Fortunately with the gen 5, the 9 feels just right. Not too tight when my fingers are slightly swollen and just right under normal circumstances. I’m anxiously awaiting a cover so I don’t scratch it up, but hoping with the lower profile it won’t be so prone to scratches. If you are seeking a smart ring you barely notice, this is the one! It’s as thin as advertised. Super light as well. ... show more

    • Fits well, monitors well
Style: Ring Size: 9 Color: Black
The sizing was perfect in comparison to the sizing kit. Color is the same as all the older generations of rings. No problems connecting to the app or setting up. Overall am getting good readings, it’s comfortable on my finger, and I’m using it to direct my lifestyle choices to help how I sleep and my activity. ... show more

Works well so far. Sizing is dead on with the sizing kit. Battery life is very good, and it charges quickly.

    • Looks great and is a bit smaller than the last generation ring.
Style: Ring Size: 13 Color: Black
Love this ring. I had the gen4 and this one is smaller and so far the battery has lasted almost a week. I’ve had each generation and needed to change sizes 3 times so I got the gen5. The analytic.s are crazy and sleep data is off the charts useful. Seems just as strong and durable as the others and the fit is perfect. The only thing I don’t like is the “notch” isn’t like prior versions it’s a little rough spot that’s so hard to find. Other than that I’m loving it. ... show more
