    Seems to be a good product. I like that the battery lasts 5-7 days and I can wear it in the shower and swimming. It did take some time to get used to wearing it! Added a cheap mini band to dress it up!

  • Great Ring - Not So Great Finish

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    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.
