I choose this ring over the Oura ring
I choose this ring over the Oura ring. After one year I had to send it off to be repaired battery issuse. Thank God I chose to get the Samsung Plus Warranty on it. However one year later I am experiencing the same issue after the repair. However, I didn't report it before my warranty expired due to being in the hospital. So they said so sorry sucks to be you. My aunt has the Oura ring for over 5 years and has no issue. Buyer be warned.
