I've tried out my grandmother's GO. For me, there's positives and negatives. On the plus side, it cuts very accurately, and seems to be good for people who might have trouble using a rotary cutter or scissors for physical reasons. (My grandmother is 85 y.o. with typical aches and pains for her age.) On the negative side, I had more fabric waste than with my usual rotary cutter. Also, you still need to cut the fabric to a size that will fit through the contraption. I'm sure others who have used it more will know more than me. Good luck on what you decide!
