    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!
