I use all the different Rotary cutters but the Go Cutter has been a lifesaver for me. I am coming up to shoulder replacements and have NO strength for rotary cutting. (I do change blades often so I always have a really sharp blade) I bought the Go cutter because I do all the cutting of donated fabric for our Project Linus chapter and I can cut stacks of strips, etc without feeling any pain. Mostly, I have been cutting boxes of 2 1/2 " strips for scrap quilts. Also find easy scrap patterns for them to make with the strips.
