I agree that previous posters generally don't like it. I tried one out. You need a big enough table and there is a lot of rerolling involved. I saw it at a show once with an expert using it. On a very small square. Of course that made it look easy peasy. In real life with something other than a tiny quilt maybe not so much. Yes do the search. You will get more info. It may turn out to work for you but get enough info first.
