Amazing
This was an amazing kit, I recent got a hug nail in my tire and wanted to save money. The directions are super easy to follow and actually doing the job was a breeze. I’m no mechanic so I fully recommend this product. Definitely cut down the unwanted rubber at the end.

Great Kit
This is a really nice tire repair kit. It contains all the parts you will need to fix a flat caused by a nail or screw. I would also recomend everyone keep a tire inflator in your vehicle. The kit is very compact and takes up very little room in the trunk.

Apparently I’m a magnet for screws, this kit has saved me a lot of money
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.
