The Purple Cows Trimmer is awesome! The only trouble I had was getting used to it. When you first get it, it is hard to tell exactly where your blade is going to cut. It takes a few uses to figure it out. But, once you do, this trimmer works! I have no trouble with crooked or uneven cuts and no trouble with rough edges. I myself prefer the guillotine blade, but the rotary works well also and holds your paper/photo firmly in place. I would recommend this to anyone looking for a new trimmer.
