I got this awesome tool as a gift from my sweetie for Christmas. I seriously don't remember how I ever went without it. I love the fact that I can quickly and easily scroll through the cartridges and view what I have with a tap on the screen. It sure beats having to open up packaging time and again, flipping through booklets and getting it all set up once I've decided what I want to cut. It has saved me tons of time. I also love that you can easily cut varies sizes of shapes at the same time without having to cut, adjust the size, and cut again. Like the others have said, it does take time to figure it out because it didn't come with a manual. (how silly is that?!) But once you do a little research on the web, you get the hang of it pretty quickly. It's simple to sync your cartridges, too. I give this 5 stars-easily. I love this little thing!
