The beans do get stuck in the grinder. But it isn't as bad as some have made out.
I t grinds nicely with infinite adjustment (this can be a little tricky but its not hard). Easy to keep clean. I love the fact that it works as well for press coffee as it does for espresso (expobar lever). Grinders like the rocky hold on to ground coffee (coffee goes through a lot of the machine before coming to your portfilter) so your half of your first shot is from yesterdays grind. The KA pro holds on to very little due to the straight path of the bean to container. It is a little louder then the rocky.
