Why we love it
A knock box is where the used puck goes: you strike the portafilter on the bar and the puck drops out in one piece, instead of scraping it into the bin. Breville's holds about 10 pucks, so a morning's shots go in one place, and the knock bar lifts out so the inside can be washed. It's stainless steel and plastic, styled to match Breville's machines, and it's compact enough to stand on the drip tray when you put it away.
Pros
- Holds about 10 spent pucks
- Removable knock bar for cleaning
- Matches Breville's machines
- Compact enough to store on the drip tray
Cons
- Part plastic, not all steel
- Costs more than a basic knock box
