    I was leery when I purchased this for my granddaughter, but she absolutely LOVES it! This was the best Christmas present I could've gotten her. I would strongly recommend it.

    I got this to track my cycle and my sleep, and it has been amazing so far! My watch has to charge every single night, so I can't track my sleep. I love that the battery life gets me to about a week so I don't have to worry about charging it every night like I do my watch.

    Works great and the fit is good. I was getting data showing that my sleep was not optimal and I was able to confirm and correct the issue with my doctor. I feel great now. Does not scratch.

    Love this, been using previous gen for a while now. Battery lasts about 6 days for me, the stats are spot on. This one runs true to size since it doesnt have the little nubs on the inside.

    I gave this to my grandson for Christmas. So far he really likes it. Great battery life and good metrics. He gives it a 4.9 out of 5 with the only deduction being that he wished they had half sizes.

    The ring has given me the opportunity to really focus on my sleep quality and over my overall quality of life. It's sleek and stylish. I'm actually encourage friends to go and get the ring as well so we can be buddies on the Oura Ring app
