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

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! 😱

Better than those with a rubber bar, quiet knock even on granite countertops, easy to clean

Awesome - rubber knock pad is durable and makes de-pucking easier.

I bought this from a review I read. But I worried about whether the knocking surface that sticking inside the cylindrical can would catch grounds on emptying, or may be too weak. The knock surface (which is rubber for impact) goes straight down, and has excellent support for the knocking, and does not catch grounds on emptying. Just as I hoped but could not see from the item pictures. So It knocks well, ejecting the puck with no side spray, and empties easily, with no loose parts.

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!

I use this every single day when I make my espresso. It's a perfectly simple design, looks good on the counter, rubber foot, rubber pad, easy clean, and pure function.

Simple and effective design but the material of the box could have been improved to a more durable and softer material to absorb the impact better. The box is made of HARD plastic. If being knocked on often everyday, I can se that it will crack for sure under a thin rubber edge cushion. The only material that can absorb the shock or physical impact the best is rubber or silicone...and NEVER hard plastic, ceramic, metal, or wood. That goes for the noise minimizing as well. I tried knocking my portafilter on the small thin rubber/silicone cushion of this knock box and it was still loud, even with the rubber cushion ring on the outer bottom of the box, just like I was knocking on the edge of the plastic trash can. I do not pack my portafilter tightly so only need one or two knocks at the most for the puck of coffee to come out. Unless the box already has some wasted coffee, the puck screen dropped loudly on the bottom when the box is empty. The size of the box is also big for me. I plan on emptying the knock box everyday as I don’t want the coffee waste sit in it without a lid for few days on the kitchen counter. A knock box is a must-have item if you use a puck screen for your portafilter, as you don’t want the screen to fall in the trash can when emptying the portafilter, or try to get it out using your fingers. Other than that, you don't really need a noisy knock box to clutter your countertop. Or just look for a knock box that is made of softer material. It will last longer that way with all the knocking and also eliminate the noise for real. The hunt for a good compact knock box is still on for me.

Great for the volume it holds (6-8 pucks) and its durability. Clearly well made and will hold up over time.

Compact (not too small). Sturdy build (it looks like a ledge, but it’s solid from top to bottom - very clever design). Non-slip. Easy to clean (inside & out). Excellent value - it was worth shopping around for a good design.

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.

Super

Perfect for what it does and is
