The thing worth knowing
A knock box is a bin with a bar to knock the portafilter against. Look for a bar covered in rubber or silicone and a base that does not slide, because knocking a metal portafilter on a bare edge can mark or loosen it.

What we have not done
We have not independently tested this product. The description above is compiled from the manufacturer’s published specification and from what the category demands, and it is written to tell you who the equipment suits rather than to sell it. Where we have no first-hand experience, we say so rather than inventing a star rating.
