    Gift for my son. He wanted black then tried on Stealth and it looked amazing. As far as sizing goes he went up a size and it fit great. Stealth color looked smooth and stylish.

    My wife was asking for one a while back and when it finally went on sale I jumped on it. She’s been super happy now having it for a month, she says it allows her to feel more confident about her health.

    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!
