A friend bought these for me a couple of years ago. It cut 1/8" larger. During my practice test the rotary cutter fell apart and I had to put it back together and it never worked right again. I found that the ruler was hard to read. It had to much goin on, to many markings and to many holes in it. So I regifted to a needy quilter and they too hated it and tossed it in the trash.
