This thing is stylish and cool. It is also reasonably functional. I'm sure you will find it to be a plus to your kitchen decor.
Negative Product Points
The knockbox is just a little bit too small to be the best match to a commercial machine and portafilter. Also, it does not have the greatest capacity -- you won't be able to accumulate pucks for weeks on end without emptying it.
I've been saddled with a hideous industrial looking knockbox since I bought my commercial espresso machine more than 6 years ago. I just assumed that knockboxes were like toilet brushes -- they do the job but you don't really want to look at them.
It looks like Michael Graves designed it, but they don't sell it at Target.
It is funky and cool looking, and now the old knockbox is in the pantry (not with the toilet brush because then it would look funny next to the toilet).
The one negative is that it is a little small for a commercial sized portafilter, and the capacity is a mite on the small side.
You can buy the same item at Starbucks, but then you have to look at that logo, and I don't recommend that.
Please note that when I bought this item it was "on sale" for $15; whether this sale ever returns I can't know, but currently it is listed on the website at $20. It may be a regular "loss leader" so check back on the website to see if it is "on sale."
Smooth, fast, and responsive -- what I have gotten regularly from EPNW.
