Although O.Sleeve may be lovingly gazing up at me as a hero, I can admit I look at O.Sleeve as a dependable friend. It does as promised and protects my Oura ring. I have a black ring and choose the clear O.Sleeve, but it does not sit completely flat against the ring and gives the appearance of bubbles. Works exceptionally well in protection, but if I was going to order it again, I would go with black for my black ring.

Just got the Matte black finish on the O sleeve it is very nice and the fit was tight but that is good as it makes it a slim fit

I was wanting to wear my ring while weightlifting and moving around heavy stuff at work, and this sleeve makes that possible. It’s snug, doesn’t wiggle around, and protects my ring from scratches. My only complaint is that the sleeve has seam lines from manufacturing that makes it a less elegant design.

Although the price seems a bit steep for a small circle of silicone, I have to say that it does the job very well. Fits perfectly around my Oura ring and allows me to wear the ring during workouts, even with barbells, dumbbells, and kettlebells.

I'm quite happy with the purchase. The sleeve fits well , the customer service was great and the packaging was nice. Perhaphs, the price is a bit on a higher end but as long as the product stands the test of time, I'll roll with it.

Finally able to not worry about scratching my oura ring. The o.sleeve fits perfectly feels nice and does its job well for everyday use such as in the kitchen and at work when handling metal. Haven’t tested in more hostile environments yet. One note is that the clear o.sleeve is subject to colour change so take note when handling turmeric et al!

Love my sleeve. It's keeping my ring from getting any more damage than it already has. Wish I would have gotten one sooner.

I wear my Oura ring all the time but had to remove it for lifting, kettlebells, gardening, and packing/unpacking for a move. This goes on in a snap, perfectly hugs my size 11 G3 Oura ring, and comes off just as easy. It's a ring-saver and I'm grateful you guys made it!

I have used the sleeve at the gym and yoga studio. I tried lifting weights with it and no issues. I love this thing!

The O.Sleeve fits snug on my smart ring. Easy on, easy off, easy clean. Spent the day staining a fence...my Oura is clean and sparkly.
