the Knock Box™ 10

The removable knock bar is a lifesaver—I can rinse it off in seconds after a messy shot. It holds the portafilter steady with zero wobble, and the pucks drop out clean every time. This thing does exactly what it's supposed to.

The rubber base grips the counter so well that my portafilter doesn't slide at all when I knock it. Cleanup is a breeze since the bar pops right off for rinsing.

I finally stopped hitting my counter trying to get the puck out, and this handles it in one solid strike. The removable bar makes cleanup a breeze when grounds start to pile up, and the whole thing feels steady enough for daily use.
