I didn't have what I would consider a serious problem with blade thickness since the shims made it possible to get the widths I needed. But the cut quality was not nearly what I find acceptable. There was noticeable chipping of the veneer of plywood and horrible tearout at the back of the cut. I know I could use a backer board to reduce the tearout but not worth it since it is chipping anyway. Spend a little more and get a high quality set from a name brand maker.
