    It’s a great product just not much of a fan of having to pay a membership premium for something that you already paid for I think if they want to do that they should include that in the price not also have to pay additional

    It scratches very easily. The ring itself is bulky. The material used on the inside of the ring can be irritating. It frequently causes a rash.

  • Great Ring - Not So Great Finish

    I love the features and ease of use. My main complaint is the finish. After two less than two months of use and taking it off any time I’m working or lifting anything, it’s still pretty scuffed up and not appealing. Not noticeable from far away, but it still bothers me. It’s faired better than my wife’s ring though. She has the gold one.
