This very sturdy tool performed beautifully right out of the box. The blades were perfectly aligned. (It cleanly cut a piece of paper.) I use it mostly to cut .030 inch saw plate steel and 1/16 inch brass plate, both of which it shears cleanly and easily. On thin gauge mild steel, it does not curl the cut edge the way aviation snips do. I have had it for less than a month and it has already paid for itself.
