Why do I say that? Well, for starters it comes with two of the largest CO2 cylinders I've ever seen; at 45 grams apiece these things look like propane tanks and are capable of pumping up a 180/55x17 to 28 psi. All of the tools-you get an air chuck, reaming tool, plug-installing tool and, of course, the plugs and rubber cement/installation lubricant-are industrial-strength and American-made. You even get a handy 5x6-inch padded storage case and, as an extra attraction, a couple of inner-tube patches thrown in along with step-by-step instructions. So based on what's included and the stuff's quality, I'm willing to bet I won't be let down when I have to actually use it.
