Yup, used one a few times, I chucked it in the trash. Sometimes the plugs stay, sometimes they don't. One time the tire spit out 3 plugs, another repair spit two plugs in less than 10 miles.. And yes, I know how to use the kit and ream the hole and insert the plug.any one have any exp. with it....good or bad.
I went with good old rope style plugs; they have never failed me. I also carry a Dynaplug kit, have not needed to use it yet. It is just a fancy rope style plug system.
