Let's face it: Some of us are messier than others, and nowhere is this more true than around the espresso machine. Whether its leftover grinds spilling from the grinder, a soupy puck from the portafilter or some drips of espresso on the counter top, we all leave a little mess after we extract. The Grindenstein knock box was designed to provide an affordable, sturdy, leak-proof and compact option for home espresso lovers everywhere. We dig its bright, durable plastic construction and think its innovative shape that's made specifically to fit on your espresso machine's drip tray is a definite plus for anyone with limited counter space. What we don't love is that, because of its compact size, it sometimes doesn't catch all the coffee coming out of your portafilter. Also, the knock bar is a bit thick for our tastes, and we find that it doesn't let the puck fall as easily down into the container, unlike its skinny-bar brethren.
