"These were very helpful to me in the decision making process of which C-ring to buy.  I have worn cheap metal and stretchy c-rings before. The metal rings were all too small and painfully tight. The stretchy ones pinched and were too elastic to constrict blood flow during sex.  I would recommend anyone considering purchasing one of King Ring's metal rings purchase a set of sizing rings, even if you've worn C-rings before and think you know your size. For one thing, these are less than free with the generous coupon which you will receive. Secondly, I found that the experience of wearing a 20mm wide ring vastly different from the narrow, cheap, metal rings. In my experience, the extra width added to the comfort of wearing the ring for extended periods and improved constriction when erect.\r\n\r\nI ordered a 50-58mm set of sizing rings and Scott was kind enough to throw in a 64mm ring as well.  Dealing with Scott was an absolute pleasure. He answered my questions amazingly quickly and was very helpful.  He really wants you to be happy with the \"real\" ring you eventually purchase and confident that it will be the correct size.\r\n\r\nWearing these sizing rings will make you even more eager to get one of King Ring's gorgeous creations."
