As far as the tool itselt, A+, it was able to break the beads on 14 year old factory Quad tires x4 both sides. Once you figure out how its supposed to work, it works. The instruction are lacking very much and the pictures are totally unreadable. Look like 100 gen picture of a 1960 snowy picture on a TV taken with a polaroid camera. SO it took a little bit to figure out how to get it connected the first time, after that great tool.
