I ordered this kit hoping that I wouldn't have to use it. Got a flat the other day on our Dodge Van and we couldn't get the spare down so I used this kit to plug the hole. It took me more time to refill the tire with the little pump I had than it actually took to plug the tire. We ran it with the plug for over a week until we were able to get into the garage to get a new set of tires. I will be ordering another kit to keep in our other vehicle.
