    This has been SO helpful! Totally game changing for me because even though I have a Garmin for workouts, I found that I didn't want to wear it all the time, so I decided to try this out and I've been so happy with it!

    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

    The ring was not what I thought it would be it would not allow me to use any of its functions without it being apart of a plan and how would I know if or what I wanted without seeing how the Oura operated so I returned mine and my girlfriend has been waiting on hers for three weeks so I don’t have anything bad to say but nothing good either look good on my hand though.
