Bests & Worsts Reviews from Amazon

Works fine, even though it took me an embarrassingly long time to figure out how it worked. In my excitement, I pulled the meter out of the faux leather case and quickly held the tip to the diamond on my wedding ring. Nothing. Hmm weird. So I re-read the instructions and tried it again. Nothing. Third time is the charm right? Nothing What?!?! My husband got ripped off! We paid how much for the ring? Lets re-read the reviews... yep they are positive, no tip as to what I'm doing wrong.....breathe.... we bought the ring from a reputable dealer..... Try again. Nope, nothing, nada. I am generally a fairly resourceful person, but I gave up. Luckily my husband is smarter than me. He came home, pulled off the rubber tip, pressed the metal part of the tip to the diamond and bingo it's genuine. Did you see the part about "pulled of the rubber tip"? Surprise, surprise the electrical current couldn't run from the hand held sensor through the rubber to the diamond..... It did cross my mind that current can't run through rubber, but no-where in the instructions did I read to pull it off and I had no desire to break my new gadget. So even if it's stuck on tight like mine was, pull the tip off and make sure you've got metal to diamond.
