    Love the ring and the technology but I returned because after 3 weeks it already had a significant amount of marks in the gold. I knew after a few months it wouldn’t look good so I returned for a ceramic one! Still waiting on the one

    I was iffy about the oura ring initially because I thought the concept was kinda silly but after wearing for longer than 2 weeks, and progressively longer, I realized better lifestyle habits forming & new features popping up to learn from. I honestly think it’s helpful.
