    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.

    I originally bought this without sizing (I got a size 8 but it was too small)... Exchanging it within the 14 day return period was simple, but if you miss that window you might be out of luck. Definitely get a sizing kit! Gorgeous ring...
