We sell and use the Stop and Go. One of the easiest to use and most efficent ways to seal a hole. None better I feel. Get an old tire and just try to use the BMW kit. Then try the Stop an Go. That should convince you before you are on a trail or a dark road at night cursing what BMW calls a tire repair kit. Don't forget some CO2 cartridges or a nice handy pump for reinflating the tire.
