I have this system. I still have to fuss with the ruler and getting the fabric perfectly straight to have accurate cuts. I like how it holds the fabric for you but you have to have the fabric perfectly straight on a mat line before cutting. I have about the same results as using just a plain ruler and mat. I can't cut shapes with it at all, one fabric piece gets out of place and the cuts are all off, for me anyway.
It is quality made. I prefer my Accuquilt Go though.

Good to know as I was thinking of getting one... I have the go but wanted this cutter as well... Just hadn't decided if I really needed both..

I use mine all the time. Intimidating at first as it is not the same as lifting rulers up, moving around, and then holding them down and cutting. The cutter is secure and measures accurately every time. Took a good supply of FQ and practiced a lot before I used it on the big projects.

Love mine!
