A nice looking and function knock box for home use.
Positive Product Points
Well-designed knock box; easy to use and clean. Nice stainless steel construction, which fits in well with my Livia.
Negative Product Points
It has the Starbucks logo on the front (but it looks like it can be scrubbed off). The marketing sticker was hard to remove from the inside back of the box, and left gunk on it.
After years of banging my puck out into the sink, I decided that I needed a knock box. Not only did I want to stop putting coffee grounds into our sewage system, but I'd occasionally knock my filter basket out of the PF and into the disposal, necessitating a scary reach to retrieve it. Enough was enough!
I wandered up to my local Starbucks (I have two within walking distance of my house; oddly enough they are across the street from one another. Odd placement) to check out what they had for sale. While I don't like Starbuck's coffee or espresso, I have purchased a number of accessories from them over the years. What I saw was a nice looking knock box for sale:
This piece is well-constructed. There aren't any open seams to catch coffee beans, making it easy to clean. It has a rubber-covered metal rod, which is held in place by two gaskets. The rod isn't fully covered, but is wide enough to handle my Livia's PF. It stands up to a good, solid "thump", which is very satisfying.
The knock box is a round shape, with a cut out in the front to allow access to the rod. The design works very well.
I only have two real "knocks" against this box. The first is that the rubber portion of the rod might not be wide enough for an E61-type PF. While it works well with the 58mm (59mm?) Livia basket, that's about the limit it will handle.
The second is that the box isn't very large. If you make a lot of shots, you might find yourself having to empty the container every day. I tend to make two or three shots a day, and find that I only have to dump my knock box about every three days or so.
Check this one out. I understand that there's a non-logo version of this box out there, somewhere.
Buying at Starbucks is always a good experience. While I don't like their coffee, the people who work there are usually very nice.

Still using it; still enjoying it. It's a nice knockbox.
