Does the job well for the price. Cuts nice and straight. The problem I have is more annoying than it really is. The first is the red top, which can be slightly lifted. But a little gorilla glue isn't going anywhere. Second, air adjustment is just a way to lose it, it actually adjusts while running. Didn't really fix it. When I have time, I plan to replace the o-ring with the same one, only thicker.
