It is hard to fit with your Quick Coupler and it is hard to fit with your quick coupler. When you remove it with one hand, the hose goes away with a loud sound and rebound as "Position" · · · I think that there are many people who have experienced such experiences. This quick coupler is strange and it is light when fitting even compared with N company, even if it is removed with one hand, it is done with a "light shock" light reaction. Previously, this type of Quick Coupler who had worked permanently in our shop was ascended and started using N company, but the above condition was honest pain. Finally, I rediscovered this product and I am satisfied because I could return to the previous situation by using it.
