Allywee, welcome to CoffeeSnobs and the BDB owners.
PUCK is cleverly made knock box.
I have a Breville Knocchi kb sitting next to my Breville Dual Boiler.
I also have the same Australian made Bogav tamper as you that was made to fit the BDB.
Although I sleep while watching TV on a comfortable ike-a chair, I donít go to their stores now as I dislike having to walk past everything in the store before buying what I want.
