I bought the IAOSEN 6 Inch Espresso Knock Box because I wanted something sturdy and practical for my new espresso setup at home. The build quality is fantastic — it’s solid, well-made, and the shock-absorbent design really does help keep things quiet when knocking out used espresso grounds. The removable knock bar is super convenient for easy cleaning, and the non-slip base keeps it steady on the counter, which I appreciated. The only downside was that the size was a bit bigger than I expected for my kitchen space, so unfortunately, I had to return it. That said, if you have the counter space, this thing is great and would make a perfect addition to any home or office espresso setup. It feels durable and looks sleek too. Even though I ended up sending it back, I’d still rate it 5/5 for quality and functionality — just make sure you check the dimensions before ordering if your space is tight! Read more

Great knock box for small space!!! It can take about 4 pucks easily (and honestly, I think it could probably hold around 6 if needed). I also love the top-off style bar because it lets me use a liner (see photo). It keeps everything super clean and makes it really easy to empty out. It’s very easy to use, sturdy, and it stays in place when you tap it. no sliding around on the counter at all. Highly recommend for anyone who wants a compact, clean, and efficient setup! Read more

This product works just like it is supposed to. The size is good for my space and I'm able to hide it behind other coffee station items. I usually set it in my sink before knocking out the coffee puck just in case there is some splatter, though as I get better at it there is not much. The product seems very sturdy. Read more

I think this is and works exactly as advertised. The bar across the top fits very snuggly into the unit which is why it works so well. Its made of a silicon material so I do believe it slightly dampens the sound a bit. Overall it is a tiny bit smaller than I expected and like so many of these canisters you have to have good aim to get the puck in perfectly. In hindsight I would have purchased a larger one to correct for this one issue. Even though I dont need a larger one due to the 2 cups I have per day a larger unit would give more clearance for the banging of the portafilter. Keep this in mind before purchasing. Read more

Wouldn't call it large. Works great for a few coffees a day for a couple. That works great for me, though and I love it. I looks good and is the quietest and easiest to clean knock box I've ever had. Read more

This knock box has a small footprint, which is good when countertop space is limited. The build feels good, it's easy to clean. Overall a good purchase. Read more

It’s solid and the material it’s made from muffles the sound of banging the expresso handle to discharge the puck. Doesn’t take much counter space but big enough to catch any coffee grounds Read more
