I have one and I seldom use it. It works. I have all the strip dies but I rarely use them because I make scrap quilts and I only need one strip of each fabric. I totaled up my investment I have over $900. Sometimes I bought a die thinking I would make the quilt and then I never got around to it. I rarely make the same quilt more than once.
I know people like it and there is a yahoo group which is very helpful. You can cut with little waste. But for me I am disgusted that I spent the money.
