I had a cold laminator that worked with a crank and is reloaded by rollers. It was convenient but it was filling and we could not guillotined. With Olympia, but we can slitting the blade is very poor quality and do not cut straight: After nearly a month, it quickly became annoying. What I like are the different formats of laminator pouches that avoid having to later guillotined, something that would not have been possible with a roller. In summary, more: several formats, time relatively reasonable heating, possibility of laminating hot or cold Cons: bad cutter, rounder inefficient angle, cold lamination pouches more expensive than hot and therefore greater consumption of electricity.
