I borrowed these from a friend after discovering a nail in my tire. Removed the tube and applied the patch as directed. It lasted for about 10 minutes and my tire was flat again. Would not recommend these unless you are patching a bicycle tire.
It does say that they are only 1 inch, I guess that I just execpted them to be a bit bigger. If you need a very small patch these will work great. I had to use 3 to get enough coverage, but they are very sticky and worked good.
