    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.

    Excellent wellness tracker. The more you wear it the more insides it gives you about your sleep patterns and how this affects your averall health. It helps you calibrate on your own your lowest heart rate so you can have over all cardiovascular health and a strong response to stress.
