Great device, especially for the price. It is very sturdy, the mechanism to hold the paper is very strong, and the lever allows you to generate enough force for even thick volumes. One odd thing that others also noticed is that the sliding holder is not fully square, and if you use it you end up with cuts that leave the paper a touch shorter on one end than the other. But I just never use it, it's a bit clunky to move anyway, and only go by the markings on the bottom plate; doing so makes the cuts come out right.
