I have one, and love it for a lot of cutting. I decided to clean out my fat quarters, so all I had to do was fold in half and cut it into 2" strips, since I am doing a scrappy quilt using 2 " strips. I cut them really fast, and if you put the unfolded side right up the the first line to cut, you will have enough on the other side to make another strip. I cut a Dresden plate quilt from it also, and it was really faster than doing it by hand. I have the hearts also, and am anxious to do something with that. But for the blocks, I don't think I will do those, just sub-cut from the strips. I bought mine mostly for shapes and strips. I think it is worth the money, if you use it. I also share mine with my friends, if they provide their own cutting mats.
