I think people who write negative reviews on this product probably do not use it as paper jams (occasional) are easy to avoid and especially to correct. No need to clamp tweezers as some claim !!! Just read the instructions and perform the operation (easy!) Fluffing. The trick is simply to turn in the opposite direction after a few uses slides to evacuate the bits of paper still present between the blades. Really not rocket science ... No problems after several months of near daily use.
