X-ACTO KS Manual Pencil Sharpener, Wall Mountable Pencil Sharpener

This pencil sharpener is unbelievably good at its job. A few short turns and the pencil is extremely sharp (faster than an electric sharpener I might add). The pencils don't break after they are sharp and it's safe to use. I joke to my students that it's the best sharpener in the world and they always try to prove the electric one better. So far they haven't been able to :) 3 issues I would like to see fixed: 1. The container holding the shavings is kind of small. It needs to be emptied pretty frequently. 2. It is so hard to install, it's almost like they want you to not buy it. The holes for the screws are almost directly under the body of the sharpener so you need to screw in the screws at an angle. REALLY annoying when installing. 3. There are no options provided besides attaching it directly to the wall or desk. My school insisted that I don't do either so I had to screw it into a piece of wood to hold in place while I sharpen the pencils. It can't be that hard to invent a way for the sharpener to hold still without drilling into a wall... Suction cups? Built in clamp?
