It works well in both domestic, say with a Gaggia Classic and in commercial situations equally well, in our opinion there is no better knock box available for the money, in fact when considering what you are about to read, it could be argued that this is the best knock box ever made. The knock box is tough and versatile, the manufacturers claim is that it is unbreakable, we have thrown one around a car park, slammed it against walls and hit one with a hammer, both are still in tact ! In use it will not damage filter holders (portafilters) when in use, or mark your work tops, thanks to the rubber footing, that comes as standard. There are similar alternatives on the market, however they tend to be lower capacity and easy to break. This knock box is very easy to clean and we carry spare rubbers for the knock bar if they ever need replacing. It feels sturdy in use and you can knock away with confidence, safe in the knowledge that the body of the box will not break.
