The good: appears to be all stainless will well machined parts. There is no plastic shear pin to worry about. While I cannot say for sure, I also believe the roller combs are metal. The bad: the roller attachment I received does not spin easily which causes immediate strain to the motor. The adjustment knob operates very roughly.
I quickly made up a batch of egg pasta to test things out (3 eggs, 2C flour). The rollers "worked" in that they rolled out the dough nicely. Unfortunately, given the spinning difficulty mentioned above, the motor heated up considerably. The ramen cutter spun nicely and cut everything just fine. In the end, given the problems with the all-important roller, I'm sending this back.
