I finally got one... I think I thought it was going to cut the circle for me and me not have to do anything.
It's not as big of a pain as using regular sissors.
My problem is my fabric keeps moving and my circles aren't perfect. Also it doesn't cut 2 pieces of fabric at the same time very well... so I have to cut one circle at a time. Do I need a better blade or something then the one it came with? ALSO it had trouble cutting thicker fabric, so I had to do that by hand.
Maybe I just need to practice more?
Someone invent a cheap machine that I can just put my fabric in and circles come out in seconds.
