it is VERY DIFFICULT to SQUEEZE the HANDLE

I bought this heavy duty stapler for a DIY project at home, putting up mosquito screens across my terrace and FL room. MAN THIS THING ALMOST KILLED ME! My hand is throbbing again just thinking about it! Grown men thought it was broken and I had to show them it wasn't broken, just extremely hard to squeeze but one you get the hang of it, it works great! It also came with plenty of staples, which I appreciated. It works well on wood and heavy projects but be warned, you will end up with a bruised hand using this staple gun....
