A little awkward at first but after I figured out how to change attachments it performs very well. I tested it on 22 gauge sheet copper just to try it out and am very happy to use it on my projects. It cuts very well, leaves no burrs and I also have a small copper point that I can use for something else. So you can use it to make holes and also cut out small circles for things. (I thought it would be a nice bonus). There are 7 hole sizes you can make.
