I have only used two patches so far, and they have worked just fine, You do have to have some tools like a buffing wheel and the vulcanizing glue and a roller wheel to make these patches work as they should, but I am happy with these patches, especially since nobody will repair a motorcycle tire, so this is Your only way to fix them.
