    Love this ! I liked buying from best buy because they have a display with all the ring sizes . I researched this ring a long time - I was reluctant to buy this one because of the subscription but it’s worth the money - love how it records my life events stress and sleep . Great it knows my workouts and works well with my Apple Watch . I recommend highly. I have the silver and amazingly after a month no scratches

    I had tried the gen3 before switching to the gen4 and honestly the fit is SO much better. Since the sensors are more flush with the ring nothing presses into your finger like it does with the gen3. So comfortable and I love the insights it gives me as well as the battery life.

    I have been wanting to get a Oura ring for a while. I really wanted to track my sleep patterns. This ring did the trick. I can see my sleep patterns, and much more. I have yet to realize the full capability of the ring and I hope to do so soon. I would highly recommend this ring, it's not only stylish but functional.

    I currently own a Fitbit to monitor my sleep, but always felt it was uncomfortable to wear while sleeping. I also read that the Oura technology was superior for sleep and it is much more comfortable. I am glad I made this purchase and now have superior technology to monitor both sleep and excercise.

    Easy to wear and provides good insights on sleep and activity. Readiness, lowest heart rate, and heart rate variability are useful things to know. Easier for me to keep it on 24/7 than a watch.

    The Oura Ring has been one of the most impactful tools I’ve incorporated into my daily routine—particularly when it comes to improving my sleep and overall recovery. Before using it, I had a general sense of how I was sleeping, but no real data to understand patterns or drivers behind my energy levels. Oura completely changed that. The combination of sleep staging, readiness score, and personalized insights gave me a clear, actionable view of my habits.

    Bought the Oura as an anniversary gift for my wife. She loves it. She’s been wearing it for a few weeks and speaks about how comfortable it is and how much data she’s able to collect and use on the app.
