Knock Box for Coffee Grounds - Innovative Barista Accessory with Improved Handling - Coffee Knock Box for Espresso Machine, Black

Very happy with this knock box for espresso portafilters. Very easy to use, great design that limits mess. Easy to empty out and wash clean after using. Fits about four pucks before needing to be emptied. The knock area is solid and very effective.

This knock box was recently rated by Serious Eats as their top choice, and I understand why. The design is entirely different from the usual bar-across-the-bin style, but works exceptionally well. Just give one good rap at the edge of the portafilter near the edge of the knockout platform (for lack of a better term) and the puck will pop right out. It's nice and deep, no splattering of spent grounds, and easier to clean with no bar in the way. It is plastic, but seems sturdy and well made; one nice touch is a rubber-type non-slip ring around the base to keep it from sliding around. Overall, a very satisfactory purchase.

If you have a Ninja Luxe Café Espresso Machine this is the knock box for you! I tried two other knock boxes that were stainless and much prettier but the portafilter was too large to fit them. So I ordered this one and it's awesome. It's the right size for the oversized portafilter and it's definitely well made. It's made in Germany and it's of good quality; although I'd love to see the same version done in a shiny stainless steel to match the machine better. Anyway, it works great! and after hours of searching it was the best one I could find to fit.

Just got this little guy today, and of course I had to make myself an espresso to try it out. What can I say? It works! Nothing falls out of the filter when you tap it against the pad. The pad seems sturdy enough to take a decent amount of abuse - I don't plan on abusing it, but its whole purpose is to have something knocked against it every morning by someone who hasn't had their coffee yet! I was surprised at how many grounds this is going to be able to hold. I was worried it was going to be too small, but it's a good size and it won't take up too much space on the counter. Looks simple to clean - we compost our grounds, so we just have dump them into the compost bin. Mine looks a little different than the picture above because it doesn't seem to have the three orange round things on the side. But I can't see what they are from here so they may just be part of the ad or something. But overall--this was a great buy at an affordable price. Thank you!

This is the perfect design for a home kitchen knock box. The little knocking lip is super sturdy, and it's got a protective coating that is a firm rubber. I usually pack my portafilter too tight, so I can't just knock the handle or I'll throw the whole inner cup out of it. I have to hit the rim of the portafilter pretty hard, and this works sooooo beautifully, in one strike, and it absorbs the sound, the bottom is cushioned so I can do it even on my wood countertop island...I love it. I have tried several other brands and styles, and they made a huge mess, because the knock bar is usually coated in very thick, spongey rubber, and the portafilter BOUNCES off of it like a dang trampoline and spews coffee grounds all over my kitchen! 😱

Great knock box. Simple and easy to use and holds plenty of spent grounds. The plastic material is very durable and easy to dump.

I love this thing. It is a great knock box in that it is easy to use to knock grinds out, it does not make a mess on the counter, it is quiet and sturdy with good dampening, and super easy to clean. It is my first knock box, but seems like it is cleaner to knock into and easier to clean than the bar variety. PLUS - you can tamp in it (rest the arm on the knock ledge, and it is wide and deep enough to hold a double shot head), so loose grinds are collected in it and not on the counter. PLUS - I have a Eureka Mignon Perfetto grinder, and elevated on a trivet, you can grind into the portafliter over/into this knock box, so extra grinds are collected in the knock box instead of lost on the counter. PLUS - Easy to empty grinds into a large grinds collection container for gardening, etc. The only downside is that it is made of plastic. It is high quality, modern and nice looking plastic, and I am sure the plastic makes it quieter to use while being easy to clean and relatively cheap, but it does look like (nice) plastic. It looks fine by my Euerka grinder and Breville espresso machine, in my marble-wolf-subzero kitchen, but if you are really into aesthetics, this is good, not great.

It gets the job done and I like it okay overall. My main issues are that you usually have to knock more than once to fully clear the grounds, and sometimes the grounds spray out with water which makes a bit of a mess. Not a dealbreaker but worth knowing before you buy. Fine for the price, just not perfect.​​​​​​​​​​​​​​​​

go for it...sturdy and does the job well

El Homeffect Knock Box es un picamarros sencillo y sin piezas removibles, lo que hace que sea mucho más facil de limpiar, incluso en el lavavajillas, el diametro es bastante grande para dejar espacio para que se pueda usar la zona con la goma de picamarros como base para presar el cafè en el portafiltro, tenga picos, agujeros o sea filtro naked. El sistema patentado de columna que llega a la base del tarro permite picar los portafiltros y limpiarlos sin miedo a que se desbalancee y tire el contenido. Contiene muchas pastillas usadas, como unas 10-15, según la cantidad de gramos que se usen y es de plastico resistente, lavable en lavavajillas y espero que me dure mucho tiempo dado que se ve robusto y de buena calidad.

Great knock box. I like the fact it doesn't have a bar across the centre and instead as a lip at the edge for knocking the portafilter. Makes it a lot easier to empty and clean.

Super

Perfect for what it does and is
