When my wife first proposed getting one of these I thought it sounded absurd. We bought an espresso machine about a week ago and after several days of knocking the grinds into the trashcan and dripping coffee all over the floor, I realized why this item would be necessary. I saw that some people complain that this knock box is too small and they get grounds everywhere, but I cannot see how that would be possible. I have used this for about three days and I have had no problems with the smaller size. I never make a mess and I am not sure why you would want a larger knock box. This fits discreetly beside the espresso machine and it is easy to clean and sturdy as well. This is absolutely necessary for anyone who owns an espresso machine, if for nothing else, because it is much more sanitary than knocking the grounds into the trash can.

This is a nicely designed and clearly durable little knockbox. A lot of people seem to be complaining that it's small. I guess it's a little on the small side, it'll hold probably 5 or 6 pucks from a commercial-sized 58mm filter before it'll need to be dumped. That's totally acceptable for me, it takes about 5 steps from my espresso setup to the garbage can so I'm not going to complain about emptying it once a week. The plastic is nice and thick, it has a glossy finish and the bar has a nice rubber coating all the way around it. The bar does not appear to be removable. I just kinda rinse it with water if it gets cruddy and then it's fine. It's cheap, it's durable and it doesn't look stupid. I'm also going to share my million-dollar idea with you guys: I have a vinyl plotter so I'm gonna cut a sticker to put on it that says "I'd Hit That" and stick it on the box. GET IT?! I'm hilarious.

I wanted something compact, and didn't like the larger ones that look like an ice bucket. When I opened the Amazon box, and saw just the box this was in, I thought it might be too small. Thought about exchanging it for a larger one, but figured I'd give it a try first. It is just the right size. I make about 3 espressos a day, and, have to empty this every other day. No big deal to me. I'm not that lazy. It also works as a nice tamping box for my portafilter. I have a Breville Barista Express, so, I imagine it would be the same for any Breville portafilter. In the end, I have no regrets with this purchase.

It's amazing to me, just how much a little thing like this knock box can impact how enjoyable it is to make espresso. Every morning I'm up making a cortado for my wife and myself with our Solis Crema, the machine isn't all that close to the compost bin so I'm constantly shuffling spent beans across the kitchen dripping hot espresso into my hand. This knock box changed all that and I can now make several espressos, knock the spent cake into this little box and go on to the next. This knock box from Dreamfarm is very well constructed. It takes a beating and hasn't shown any signs of slowing down. It is large enough to hold 5 or 6 pucks but still fits under the overhang of the espresso machine. I'm so glad I bought this, it has improved my coffee life considerably!

This knockbox is the perfect size for me as I didn't want to take up a lot of counter space. It's about the size of a Hellmann's mayo jar only shorter. I find it'll hold 5-6 pucks before I need to dump them out. It's got a rubber ring on the bottom so it doesn't skate off the counter when you use it and it's built like a tank. Dishwasher safe to boot! All-in-all a very nice knockbox.

i've had this for a few weeks now and I'm very happy with it. For me, it's the perfect size and really would not like anything larger. It holds several days worth of grinds for my 2 person household, and just works. I'd buy it again for sure. I wish there was a ceramic or stainless version in the exact shape, but the plastic is high quality.

Love my Grindenstein. It's rugged, gorgeous, and has been helping me recycle coffee grounds to my garden for more than three years now. I also love the customer service from Dreamfarm, the manufacturer. I had an issue with one of the end caps, and they went above and beyond expectations in addressing it. Flawless customer service from a company that cares about its products and the people who buy and use them. Wish more companies took a page from Dreamfarm's customer service manual.

So before this was bought, there were empty espresso pucks all over the place in random dishes, now that we have this.. each puck is neatly and easily dropped into the knock box.. and eventually discarded. Super easy to use with our Barista Express, thought the opening would be too small, but have never had a misfire yet, 100% recommend one of these for your home.

The size is great as it doesn't take up too much counter space and it does exactly what we bought it for. It super easy to clean and feels very sturdy and durable.

After about six pucks you'll want to think about emptying it, so totally impractical for a coffee shop or cafe, but it's sized perfectly for the home barista's countertop. This is a solidly-built little knock box that won't rattle or otherwise amplify the thwack thwack pounding of your portafilter. When I'm wanting to be extra quiet, though (preparing my wife's first, morning espresso drink), I've been known to hold it in one hand while knocking out the puck.
