These are high-tech condoms which means you must use lube. I bet the users that reported failures did not use lube. This condoms without lube = disaster. These condoms when used properly and with lube are excellent, almost as thin as the Crowns, and exactly as thin as the Kimono Micro Thins. They re soft, silky, smooth and strong, not to mention sensitive. They are also wider than regular condoms, almost as big as Magnums.My girl and I wrapped one around a bedpost as a test to see its strength.We stretched it. It did not break until after an insane amount of abuse. If you break these, or they pop or they don't fit, you may not be using lube. If you don't want to spend money on lube, then use the regular Trojans 'cause you will break anything thinner than a rubber glove.
