DreamfarmGrindenstèin Sturdy, Compact, Modern Space-Saving Espresso Coffee Grind Knock Box - Black

I was looking to upgrade my cheap knock out box. The one I had before started falling apart,This is sturdy, goes in the dishwasher, can hold about 10 pucks, is very compact, and does not slide around due to the rubber grip at the bottom.You bang the portafilter directly on the rubber part, so the puck will break into two (most of the time).It works as expected, nice and firm but also wouldn't damage my expensive portafilter or basket.I imagine it will last for many, many years.

I had misgivings when this turned up. My ECM machines portafilter handle / basket is 58mm and looks massive in comparison to this knock box.I should not have worried. This works perfectly. The coffee puck just rolls off the strike bar and falls whole into the box. No mess. I expected exploding coffee puck everywhere upon striking but not the case.It’s sturdy, doesn’t slide across the worktop and looks very unobtrusive.V pleased.

Very useful. After continually making the kitchen sink filthy and enraging my wife, I decided to purchase a knock box. This one seemed to be well received on the internet so I took the plunge. It's a neat little thing and quite pleasant to the eye. The outside is a quality gloss plastic and the arm is coated in rubber. There is a grippy rubber base to stop it from moving and it has a decent weight. I've almost perfected my 1-hit-knock! Fits nicely under the coffee machine for storage and looks in keeping with most machines.

Fantastic. This coffee knock box is brilliant. I am very pleased with it

Why do I need this was a question I asked myself a few times. If you're reading this you're probably thinking the same. Let's be honest, it's just an expensive bin with a rubber bar across the top.My coffee making routine would see me unlocking the portafilter, walking across the kitchen (dribbling coffee or leaving a small trail of used coffee grounds), getting to the bin and trying to find a spoon, then spooning out the used grounds (which never came out in one go), sometimes dropping the basket into the bin............ I got bored of this after a while and put a small Tupperware tub next to the machine but I still had to spoon out the grounds. This was okay, but still not a perfect solution.I bought the knock box and it was delivered the next day. It was slightly smaller than I was expecting, but on reflection who wants a load of used grounds hanging around. Plus, space is at a premium on my worktops. I've show the box next to a pound coin so you can gauge the size.This is a quality item, it just feels nice and solid. You can give the portafilter a nice whack on the bar (which stops the basket falling out) and the grounds are 'ejected'. The basket is then ready for fresh grounds - job done.So, a small Tupperware tub or a walk to the bin with a spoon will do the trick, but this in my opinion is way better. Plus, I empty the use grounds on the garden and its dishwasher safe.I'm happier now that my wife doesn't grumble about my coffee trail across the kitchen floor.

This does exactly what it is meant too. It is small - about the size of a 500g coffee tin (what I used to previously use). As it is home use this size seems perfect. Big enough for a couple of days of use and easy to squirrel away on the coffee machine (or in my case a window sill). Rubber knock won't damage the filter & is robust. Easy to tip onto garden (coffee grinds help improve acidity of soil for azaleas, etc).Bought from Amazon warehouse so had a couple of chips on plastic top, but not noticeable. Unfortunately one of the endcaps for the bar going through the rubber knock is missing so you can see the steel bar. Warehouse described it as good condition so I guess good means missing part! That was only disappointment. I didn't want to pay full price as it is a lot for what it is. However I would recommend it & would now pay full price.

I tend to stick to only good / high reviews when purchasing on Amazon, and this product was up there with the best of them, so I had high expectations. When it arrived I was surprised how tiny the knock box was, to the point I was a little concerned. Once unboxed, you immediately feel reassured, yes it is on the compact side but it's plenty for an average household and their coffee each morning. You also immediately realise the box oozes quality and has the correct amount of sturdiness, which at this point I was bowled over. To finish off, the box will always be nicely secured via the inclusion of some welcomed rubber trimmings on the underside.Highly recommended and a must for those at home baristas.

Good quality plastic, the bar is solid so no worries about giving a firm 'knock' to bash the puck out. However, the problem for larger 58mm portafilters is that the bar is central which does not give space for the puck to be cleanly knocked out... the Sage knockbox had a much better placed bar... giving more space for the puck to fall out without obstruction. So with the Grindestein it often takes a few bashes and is messier to get the puck out.
