    So far so good. I wish there was more capability in syncing with other health apps but am impressed at the amount and level of information that the ring provides.

    Great Christmas present for my wife, she loved it although I was unaware the size is not for the ring finger but for the index finger. Best Buy made it very easy to switch it out for the correct size!

    I think it does what it says it does. I've only had one week. I like it- I struggle wearing a ring all the time but I'm getting used to it. It's very comfortable. I switch between my forefinger and middle finger. I'm still getting used to the app. I do think the steps are overestimated.

    The experience having this ring was great, i feel its a great upgrade from using a smart watch. The only down side for me was the variety of sizes. Size 6 was to tight & size 7 was to loose

    Best.gift.ever. Battery lasts a long time. After four days it’s still at 50%. I’m tracking my sleep and trying to improve. Now that I have this ring, I understand my sleep patterns and have suggestions on how to improve. Looking forward to more health data in the future.

    I bought the Oura ring for my because she washed to track her sleep. She has had the ring for a few weeks now and she absolutely loves it. It tracks everything and monitors way more health markers than I could have imagined. I would definitely buy it again.
