I love being able to make multiple cuts without moving the ruler, the way the slits hold the cutter and the grip on the ruler. It takes a bit of patience and initial learning to get the two folds parallel for strip cutting, but for me it is definitely worth it. I use removable stick on dots to mark my cuts. In the photo the two colours show the first and second cuts for binding strips. My only complaint that for squaring purposes, the marked lines are too thick for ideal visibility. But that complaint is not enough to reduce my rating.
