I actually have quite an extensive set of the Marcato Atlas 150 and enjoy using it quite often. I mix my pasta dough with my KitchenAid mixer and then proceed to make some fantastic pasta. The MilleGnocchi is an attachment for the Imperia machine, which I do not have, so after a little modifications, I have adapted it to fit into the Marcato Atlas machine and it works out great!I have used both hand and electic cavatelli makers in the past so I am familiar with how they operate, and the MilleGnocchi is not very different from them, only better!! After using my KitchenAid sausage stuffer to extrude the pasta dough into a nicely formed 1/2" wide and perfectly fromed "string" I then proceeded to try all three settings of the MilleGnocchi.First, keeping the width of the pasta to (around) 1/2" will ensure that the noodles formed will be the right size and not have any crossover makings from the other settings.Second, feeding the pasta is very easy, but before I did that I springled some regular all-purpose flour into the MilleGnocchi in order to prevent the dough from sticking and jamming. I tried all three settings and the MilleGnocchi produced perfect formed Rigatelli, Gnocchi Sardi and Cavatelli.Third, although it is not a "negative" comment, one limitation of the MilleGnocchi over the other hand or electric units is the limitation on the size, due to the multi-setting of the three different types of shaped pasta that this unit can make. HOWEVER, that being said, I am far more pleased with this MilleGnocchi that I am with just the Cavatelli makers as it is much more versitle and even fun to use.The unit itself operated without any mechanical problems, and my modifications were only made to the bracket ends that attach to the roller unit. I wish that Marcato made a similar unit, but I am happy with this as it is.
