I have one - the 12x12 - June Tailor. I haven't used it yet, but I will be making 2-1/2" cuts for my sashing soon and know it will work great. Time saving also. I got mine at JoAnn's with the 50% off. Even if I don't use it all that much, it is a good thing to have on hand, and if you bought it with 50% off, it still is a good investment, especially with the sashing for a quilt - very important piece of quilting apparatus, I would say.
