When I ordered this compressor I wasn't under any illusions that it would be perfect in terms of build quality ,given the budget price. And sure enough, on assembling this tool, the feet were completely out of true. Tried everything, but to no avail. It rocks almoner the place on a perfectly flat garage floor. As for the operation of the tool, you couldn't ask it to do any more. I run a professional garage dealing in high performance cars, and have used it four times in a week, already. With regards the feet, well, some heating, drilling, and realignment will be needed. I could do without that!
