input with options: Title: Misleading Review: I have just received this ring today and upon opening its package my first thought was: "Is this a joke? Did they send me the wrong ring??"Take a close look at the picture and what do you see? You see a very, very heavy looking ring that looks like it can take a beating. What do you get when you actually get this ring? You get a thin little band that is slightly less then 7mm wide. 7 millimeter = 0.7 centimeters!! How do I know this so easily? Because I have rings that are 7mm wide and this is not even that wide in comparison! So thats right! You get a ring that is less than 1 CENTIMETER WIDE!My advice, look elsewhere for a ring. This thing is so frail that I could snap it between two fingers. I have had this ring in my wishlist for almost 2 years now and when I finally break down and order it, I find out that it looks absolutely nothing like the picture advertises. Talk about severe disappointment. Old Glory, you have lost a customer today with me. Is this product review negative?
