I haven't tried this cutter, but go to their shop (Quiltbug). The people that run it are wonderful and they use and test the products they sell.
I will have to run out there after Thanksgiving and ask them to give me a try at it though.
They have even let me try products and told me to buy it at Joann's because it would be cheaper with their (Joann's) coupon than it would be at their shop. Now that is customer service!
