I was 5 for 5 with the Stop and Go. Swore by it and never left without it on a trip. Then I had a very annoying day in Utah where the plug kept snapping off...apparently the hole was too small, even after enlarging the hole. Went thru 4 plugs that day. Finally, with a dead flat at 10:45 on the ET Hwy, I busted out the BMW kit. Since I'd never used it, I had to find the English Drrrections (great trip planning, right?). Guess what...first try, it held all the way to Sacramento where I had the tire changed. I'll probably still carry the S and G along with the stock kit, and have added this
to my kit for the next trip.
Oh, and dont forget the 12V compressor.
