    This is the second time I purchased this ring. Love the way it tracks everything. I lost weight and my size 12 rose gold no longer fit so I purchased size 8 different budget so I went with this color. Not as feminine as I would want but still love it.

    This is surprisingly comfortable. It's very small and isn't super different from any other ring. If you're going to wear a wedding band anyway, this one tracks sleep and heart rate very well.

    I bought this in conjunction with one for myself as our daughter recommended. He was pleasantly surprised and now relies on it. We compare our sleep and other health tracking with our daughter as well and it's so precise! Our iphones also share information which is an added bonus. I would highly recommend and yet our only concern is that this finish has many fine scratches. It's likely impossible to not have scratches as we all work with our hands.

    Absolutely love this ring , the features are great only con so far that yes it is subscription based. It feels premium , looks premium , and people have definitely noticed this new accessory on me. I been asked so many time about my experience with it and its only been one week. If you pair this with other fitness tech that can shear data with each other then it helps you be even more on top of your health. Is it needed? Honestly no but you can say that about fitness tech. At the end of the day food and exercise with more concentration on what you put in your body or fuel your body is more important than tech.

    I have been using my new oura ring to track my sleep in conjunction with my apple watch ultra and it is so nice to have something that is minimal but tracking my 24/7.

    I got this to help track my sleep and stress in connection with my autoimmune and anxiety issues. So far it has been monumental in signaling a flare up, and it is helping my doctor and I with awareness of side effects of new medication. I did go on Amazon and get different covers to protect it and love it.

    This rings tracks so much and more. Battery life is good for a 4-5 days. Don’t want it to get below 20% or it will damage battery.

    I am genuinely obsessed with my Oura Ring. It’s lightweight, stylish, and the insights are incredibly accurate. I love waking up and seeing how my sleep, recovery, and stress levels look—it’s changed how I take care of myself.

    Love my ring but bought it too small. Needed to switch to a different finger. But the info I'm getting on my sleep is super helpful. And I like the look of the brushed silver.

    The part I really like about the ring is that I can get information when I sleep. My watch is too bulky to wear at night. Plus with days of power reserve, I don't worry about it not lasting the night. This really allows me to get full day feedback on my health metrics.
