I pre ordered the Go as soon as I saw it announced by Accucut. It's years old and still going strong. It's as important to me as my sewing machine. I have had a few dies that didn't cut all the way through but I have learned to go back and forth over them before the die discharges to get the clean cut. I seldom pick out the threads in a die until they stack up and easy to get out. I stock up mats when I find them on sale. I've never gotten a mat included with a die unless I ordered it separately. I have cut everything that can be cut on it but I can get another anytime so I don't mind trying out new things with it. I spray Static Guard on the mat and die and that stops the fabric from clinging. I have used the Sizzix and other models but like the Go the best. None of the home die cut machines are perfect.
