    Originally purchased this based on the amount of different things this ring senses its gone above and beyond my expectations. It was quite interesting to see it tell me while I was sick that I might not be feeling well and should rest until I recover.

    Wonderful for tracking sleep metrics. Not as good for exercise tracking. Overall comfortable but takes time to get used to the thickness. Glad I made the purchase.

    I had Gen 3 for a year and upgraded. My biggest dissatisfaction is how you have to constantly adjust the positioning to align the sensors. Rings rotate throughout the day, leaving the sensors misaligned and not providing accurate readings. After every hand wash and throughout the day I have to adjust it. They should add the sensors throughout the ring. Oura needs to stop trying to be an activity tracker and add the sleep sensors throughout the inside of the ring so we can just wear it and never think about it. All the professional reviewers agree this is an excellent sleep tracker, but nowhere near a good activity tracker. Once Oura focuses on just tracking sleep, I think the ring and features will be better. I am also worried about the gaskets falling apart like it has been happening to many customers.

    So far I love it! The find my ring feature should be updated or make it so we can play a sound just like the iPhone. It can be pretty difficult to find if missing.

    It’s just “okay”. I don’t see the value in having it, especially if you have an Apple Watch. Also, the ring scratches very easily … the paint comes off easily.
