Hitachi EC16 2-1/2 HP Compressor, Oil

I bought this compressor about 2 months ago and have had nothing but trouble with it. The Hitachi compressor I got first was broken in shipping and did not work so I sent it back. The next compressor arrived and it to was broken in shipping, but I decided to keep it since it was still working. Now that I have used it for over a month I've decided that my Ten Year old Compressor from Montgomery Ward believe it or not works much better. The Hitachi compressor takes forever to get up to pressure and if you are sheating a roof or a floor it will not keep up with even one nail gun. Even framing walls with only one nail gun the compressor can not keep up I have to go back with a hammer and finish driving 50% of all the nails. Do not buy this compressor unless the only thing you plan on doing is making bird houses with it!
