Bumper tamper and mat, Baratza Vario grinder, Quickmill Vetrano
This is a great utilitarian knockbox.
Positive Product Points
It is the ideal single user knockbox. It is sturdy, small enough to fit under the grouphead when not in use, and dishwasher safe. It holds up to 5-6 pucks easily.
Negative Product Points
At first I thought it was a bit expensive for a plastic tub and a rubber bar, but it works so well it is well worth the money. It definitely isn't a Reg Barber in the looks department.
I purchased this when I bought my espresso machine as part of a whole slew of accessories (tamper, mat, brush, bottomless portafilter, etc.) I'd heard good things about it, and while I longed for a beautiful wood box, I was kinda pushing the SO acceptance factor by taking up 24" of counter space with the rest of the espresso gear, so I decided it would be prudent to compromise on this accessory.
I couldn't be happier (ok, maybe I could), but it works better than I thought it would, and I've really grown to appreciate it's diminutive size. I can "compress" the espresso set up down to about 18" of counter space by placing the knock box under the group head and the mat, towel and brush under the Vetrano.
I bought my entire set up through Seattle Coffee Gear. Prices were decent and they shipped quickly.
