the only down side is that if I use thin chipboard (aka cereal boxes) it tends to cut through the score. Easily solved by gluing paper over it. I'm also going to try substituting something thinner for one of the cutting boards to alleviate the pressure.
I just love this product. It allows me to display my pictures without having to buy a frame. Works better if you use chipboard rather than heavy card stock. I haven't used it with grunge board yet but I'm sure it would be good as well.
I am giving this a three star only because I am having issues with it cutting all the way through instead of scoring, I have tried this die on the Big Shot, Bg shot pro, and the Vagabond, so all and all I need to play a bit more till I get it right, which is odd, with Sizzix-Tim Holtz Bigz because usuaally they are awesome first try, so it may be just a user error on my part, the jury is stil out for me on this one.
