I have one I put in my bag and take to work with me so I can square up squares.. I am a cashier at a mini mart. The one counter is the perfect height so I put it there close to the register counter so customers really can't make out what I'm doing I get my work done when I get in then later when its slow I pull it out and trim in between customers. This works great. I like the board next sale will get another for back up
