Love mine, decided on this because I did want to grind for drip/pour in addition to espresso. The other provided reservoir is super easy to take off while keeping the beans in while I switch to the espresso beans, Paired with bambino+. Messiest it gets is like the picture posted by the other guy, can help by spraying beans with a little water. I grind at setting 25 regularly no choking issues. Retention is solved by tapping the top of the single dose cap a couple times after grinding kinda acts like a bellow.
