Query: Piece of Junk!!

We have two of these guns and they just don't perform. They are actually falling apart and they are only a month and a half old. Nails jam in the gun and the worst thing is they actually fire nails when you attach the air hose to it. So when you see someone at the beginning of the day hooking up the guns run for cover and I AM NOT KIDDING.If you are thinking about buying this gun reconsider and spend the extra money on a Hitachi.
