I bought this tool at my LSS for quite a bit cheaper than it is here online. Considering what it does I would never pay 50 bucks for it. But I will say it is a handy little tool. It shreds cardboard as well as cardstock. It makes it easy to shred paper along the edge without having to worry about the paper tearing too far. It is a little loud, like a pencil sharpener. But still a nice tool to have.
