Honestly, I’ve owned a few guillotines over the last 8 years, from rotary cutters to the slicing action and this one is the best so far. It is supremely comfortable to operate and slices through paper, (including cotton watercolour) and card like butter. The guideline markings are clear and substantial and the base is solid. Because of its compact size it is easy to store (mine goes under my sofa). And the bonus is that it arrived, well packaged, the next day. I am one happy little artist.
