Review on Pre Glued Puncture Bicycle Glueless Portable by Steven Cox

I like the size of the patch kit and it is easy to use. There are no instructions on how to apply the patch. I roughened the surface with the supplied metal grinding tool, found a patch that matched, peeled off the protective film and stuck it on the pipe. Pressed on and around the area and left the tube on for two days. I pumped air into the tube to see that the patch was leaking and contained only enough air to inflate. Installed the tube in the tire, slipped the tire onto the wheel/rim and inflated to 50psi. After 30 seconds something burst. They removed the tire and tube, and the patch flew out of the puncture being repaired. It looks like the material is not hard rubber.
