Love mine! It is so much safer for me to use, not to mention more accurate long cuts. I use mine on top of my June Tailor Shape Cut mat to keep the mat from slipping. It does require some adjustment as you do not use it in exactly the same way as a regular ruler. My bet is that the quilter who does not use hers was unable or unwilling to change how she uses her rulers. I made myself adjust because I can see the safety benefit for myself, especially as I grow older. The YouTube video does a good job of demonstrating how to use the ruler. It really does not slip at all once you press down on it. You do need the correct height cutting table to use it properly.
Edit: this ruler is not used to measure. It is used for cutting. I think that throws some people off.
