I did not know if I would really use one so I decided not to get the GO. But then the GO was my bday present from my family. It was an adjustment to get used to having this expensive toy. At first I would have to remind myself to use it bec I am so accustom to my rotary cutter. The more I used it, the more I liked it ..... now I absolutely love it!! It saves my arm, my hands, saves me time and my cuts are PERFECT! I am so glad now that my family got this tool-toy for me. I have since purchased additional dies ... and have been able to find each and every one on sale.... a great idea!
