Use this mill for two weeks for my portafilter machine and get great espresso! Per cup I need 30-40 seconds "handmade", which I think for an occasional espresso fine. The grinding result is very consistent, at least for fine espresso freeness. Setting the grind is quick and easy. Tip: turn adjustment screw completely and then reopen 10 Clicks far as the starting point for espresso. Then gradually make progressively closer to depending espresso result or continue. For the 40 obtained here the result of grinding significantly more expensive electric mills. The construction of the mill is made of plastic, let's see how long it lasts. So far, an impeccable and inspiring product.
