    Not a "smart" ring
  

*by T***M on Reviewed in the United States on July 27, 2020*

Not a "smart" ring. with all the BS you have to go through to get it to do anything you might as well open your phone.  I was under the impression it would do a lot more than what I was lead to believe. Have to admit it is a nice ring but not anywhere near what i thought it would be
