It is pretty good.
The magnets hold the top and bottom together on either side of the paper but if you're not careful your paper can move. It works best with a foam mat so the tool goes all the way through. It cuts pretty clean.
I definately found it easier to use the little sticky end bits on the ribbon to thread it through (a few come with it).
I think I'll get another design....
I purchased two of these tool and sencil and I like the efects it makes on the page. I wanted to use them on every page I made yesterday but I had to resist. I might have to got on of the other ones.
