Don't get me wrong these kits save lives it's just that this model doesn't work that well with the manual insertion tool the manual screw type (in I have BOTH types so I know what I'm talking about). If this was a manual paste tool review it would be 6 stars! , and car tires. I once had to put two dowels in the same hole to get to a tire shop because I broke the shackle of a LARGE padlock on my truck tire. I will be buying another set or two, I need one (and a small supercharger) in every car I drive!
