    This ring is awesome as long as you go into it with proper expectations of what a smart ring was originally designed to do. Definitely get brushed silver, though, because it is the only one that hides scratches well.

    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.
