I bought the Trimmers and Guillotines to crop plain paper. With the trimmer, I can not make a single accurate cutting - the edges of the paper were separated wavy or crooked. Already simultaneous cutting of 4 sheets was not really easy. The triple winder is a good idea. Unfortunately, this part sits so shaky in the guide that precise work is only possible with difficulty. Metal is the way, unfortunately, only the base plate. Everything else from plastic! Part went to recently test back (unfortunately with private postage because no return slip came with).
