Review on OLFA 9911 Compass Circle Cutter by Kristin Bennett

I bought this cutter hoping it would cut small circles; However, the plastic side guard that prevents the tip from piercing the paper raises the blade to a height that does not allow cutting a proper circle as it is no longer. Neither the blade nor the tip can be adjusted in height to eliminate the discrepancy. Also, I thought the size lever would show measurement increments, but it also lacks measurements, so you'll have to guess the size until you get it right.
