    I studied this for q year before making my purchase. I must say if you are a health junkie like me and like to keep track of your health markers this ring is for you. The silver tone is gorgeous and I find it does not scratch easily. I still bought a cover for it just to protect it.

    I thought it was silly to spend this much money on one of these but I really wanted to track my sleep and temperature and knew this would be a little more accurate than a smart watch. What’s nice about this is I also have a Garmin watch so whenever one is charging I have the other for a back up.

    I got this ring to track my period and to use as birth control. It is still getting used to my body so i can’t yet if that worked, but i do like being able to see my sleep patterns, it also caught that i was sick. It measured my temp as well and that pretty cool.

    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.
