Reviews

Customers said this knock box is well-built with great quality and aesthetics. It's praised for being "much quieter than expected" and having good capacity. Most appreciate the size options and stability. Some feedback notes the crossbar placement can interfere with grounds disposal and logo durability issues after washing.

  • Much quieter than I expected, holds more than I expected, and handsome as the devil
  • Solidly constructed and is a perfect fit for the space that's available
  • Works perfectly and looks great at my espresso station

The small is perfect for a home coffee station that makes 4 to 5 shots a day. The steel is thick, and the design looks great with my entire setup.

The bar is in the wrong place

The bar on this knock box runs across the middle of the circle. So you have to knock your grounds onto the bar (to at least some extent); there's no way to knock the grounds into the box without getting at least some on the bar. That's very annoying. I'm ditching this one for a different one where I don't have to make a mess every time I knock grounds.

My Lucca A53 Mini and

My Lucca A53 Mini and Ceado grinder occupy a good deal of space on my counter and the small Lucca Knock Box was a great find. It's solidly constructed and is a perfect fit for the space that's available.

Attractive and stable, easy to clean. If I had designed this, I would have put the cross bar further back, so when striking the compressed grounds it would not be impeded by the bar.

Trust the process! I looked at the box and thought no way is this going to work - I'll have grinds all over. Well - it worked great; it looks better than an old plastic bin and I no longer have a mess on my coffee station!

I love the capacity. And the rubber on the bar seems like it will last. So far (only about six weeks) so good. That it looks good is an added benefit.
