Apparently I’m a magnet for screws, this kit has saved me a lot of money I drive a lot and somehow I manage to find every screw and nail on the road. At this point I’m convinced my tires have some kind of magnetic attraction to them. Because of that this tire plug kit has actually saved me a lot of money. Instead of constantly going to a shop every time I pick up a screw, I can just plug the tire and get back on the road. The tools in the kit feel solid and it comes with everything you need to do a basic tire plug. I’ve used it a few times already and it works exactly how it should. The plugs hold well and the kit is easy to keep in the trunk so it’s there when you need it. If you drive a lot like I do, it’s honestly just a good thing to have in the car.
