I bought one about three years ago at full retail cost because I was tired of my hands, neck and back hurting after cutting fabric. I really enjoy it and use it for most all my quilt cuts. The mats last a long time, for me anyway. I am still using the same mats that came with my Go. I always move, angle, or scooch it a smidge to not cut in the same place. I buy the dies when I find a good sale. I'm excited when there are new dies to choose from. It's not for everyone but I'm sure glad it's for me.
