Why go to a tire repair shop and spend a fortune when you can do it yourself. However most people don't want to be bothered but for us do it yourselfers this patch set was great. Comes with various patches all in different sizes. If you're not familiar with fixing a tire it's really easy and honestly a scam getting it done. Fun fact the gray glue on the bottom is actually activated when you drive heating up the patch and vulcanizing it to the tire but it doesn't hurt to actually use some rubber cement to seal around the patch to prevent future leaks. I ended up having to use these on one of my motorcycle tires when I ran over a pallet staple, for me the biggest patchwork and once testing and rebeating the tire there was no leakage. Good price for the amount you receive and cost less to repair it yourself than taking it to a shop
