    Fantastic, took me a while to get used to sleeping with it but so far so good. I have been rough with it and is not scratched. I do not lift with it, it fits good. I got a size 10 and it fits on my index finger just right. Not too tight not loose.

    I ordered the wrong size on my first one, the sizing is a little different than actual ring but once I got it I loved it!!! I wonder how long it will function but I have had it almost two months and I love it… I use it in cold plunges, hikes cooking cleaning etc and it lasts great!! I don’t use lotion or anything in my hands I take off if I use hand sanitizer but it is worth the effort for the information it gives you about what your body is doing!!!

  • A LIFE SAVER!

    In May I purchased the Oura ring3. I was a healthy 50yr old woman with no health issues. The app kept telling me I had no resting heart rate and was in tachycardia from day 1 so I thought it didn't work and returned it. The following week ended up in the ER with a heart attack. My blood pressure was 233/110 and my heart rate was 107. The data this ring was providing me could have saved me a lot of pain if only I chose to believe and act on it. I repurchased the Oura Ring4 and trust it completely for the accurate health saving data it provides. I highly recommend it!

    A great tool for doctors and yourself. It gives you a great insight to how your health is. You’re overall sleep and your stress. This can help give you a sense of peace and I can also help show your doctors what you go through.
