Sage The Knock Box Mini 5 "What an addition to the "coffee station"!" 07 May 2018 "I have been the proud owner of an espresso machine for many years - an appliance that gets used many times a day - but have never thought to get a 'knock box' before. It has revolutionised my coffee making experience; the coffee 'puck' is released into the box with one tap and is kept separate from the other kitchen waste, meaning that my kitchen bin does not smell and I have crumbly coffee grounds to add to beds and pots in my garden. Thinking about getting one for everyone I know with an espresso machine! A note from the team Thank you for placing your review and for your wonderful tips for the used coffee grounds. I'm so pleased to hear how happy you are with the knock box.
