My husband bought me the GO for my birthday! I saw it at a LQS and the lady showed me how to use it and such. I was hooked. I have bought four dies thus far, the mats are interchangeable. I absolutely love it, beautiful cuts! Percise, I just cannot say enough. I also bought a Dresdan Plate Die, I would have never done this pattern if I didn't get it. What ease. My suggestions, look around for best price and buy it! Feel free to PM with any questions.
