I have purchased many paper trimmers in the past and this was my first Guillotine trimmer. I love it! It cuts a nice crisp edge when cutting single sheets of paper. I tried cutting multiple sheets of paper at one time and this trimmer would not cut through multiple sheets without tearing the paper. When cutting a single sheet of cardstock or 110# paper, it cuts beautifully. Even the tiniest sliver of paper is cut perfectly. I would recommend this trimmer.
