I don't think there is anything special about this set but I'm happy with it so far. It has easy to use instructions. The tools appear to be quite durable. The case that comes with it fits snugly in the underbody compartment of my 2007 Mazda3 hatchback. It takes some force to insert the plug into the tire and then remove the tool. If you plug a puncture in one of the car's front tires you can leave it on the car, but I can't imagine fixing the rear wheel while it's on the car. You will not find a suitable position to exert enough force on the instrument. I took my time and probably only spent an hour fixing one of my car's front tires. In comparison, I could easily spend two hours in a tire shop and they would probably make me buy a new tire. So I would be happy if this kit has already paid for itself. It comes with plenty of plugs, which will likely be enough until cars become illegal. I will update this review if it turns out I have any issues with the fork. According to the instructions it's only a temporary fix but I'll try my luck and see how long it lasts.
