    Excelent. I got it for my kid, and he loves it. Sleeps with it all nights and gets him the right information. He later uses the data to improve his gym routine as well.

    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 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.

    So far overall good product for health tracking, biggest cons are the monthly subscription and it does scratch easily. It’s nice having a health tracker that isn’t a watch.

    My review is based on my personal experience, but my purchase was based upon my daughter's recommendation! I read reviews prior to purchasing also. It has helped me to monitor my overall health, heart and exercise! I have also had the best experience with our Best Buy salesperson who also said I would be happy and he was correct! I would highly recommend it. MY ONLY CONCERN IS THE RING GETS FINE SCRATCHES!

    Its a very interesting ring and it has several features. It is similar to a fitbit but i think more accurate. Its nice to have the oxygen level, glucose level, and the advisor to suggest things.
