I have one, I needed something to help with accurate cuts. It's okay but I still had messed up cuts. My pieces were always off cut to cut. It's very heavy and made to last. The mat is high quality and the fabric holder is nice. I have it out on my cutting table and use a regular ruler not the guide that come with it. It's expensive and for a little more you can buy the Go die cut machine which I have now and have accurate cuts every time.
