Review on Notre Fighting Irish Metal 4 Pack by Johnny Wheat

This is a metal plastic cup with a spring inside that is designed to engage the tire valve threads. The first set was received, two were screwed tight, one pulled out with ease, and the fourth barely touched the threads. Being a struggling Irishman I brought her back for the second set. Exactly the same results. In fact this time the tire valve was at the top of the tire, I put the cap on and as soon as I let go it fell off by itself.
