I've owned several products from ICS over the years, and I've always considered them on par with Marui as far as quality is concerned. I currently have one of their newer mp5's and am very happy with it. Metal body, great motor, fast trigger response and ROF, and a breeze to disassemble. All of this for only $215! I have heard of a few cases of trouble here and there with tappet plates, wire connections, ect., but that was a few years ago. From what I understand, to date, they have made the necessary changes to work the bugs out. They also have some really great innovations you can't find on other brands, like a cocking tube laser for their mp5, and a split-style gear box on their m4, so you can change your cylider set right there in the field with nothing more than a phillips screwdriver. This year they've even come out with a 3-shot burst aeg! Some of their guns are a little pricy, but they boast cutting-edge technogy. Also, you may have heard of their sister company, VFC. 'Nuff said?
