Normcore53.3mm Puck Screen - Lower Shower Screen - Metal Contact Screen for Espresso 54mm Portafilter Filter Basket - 1.7mm Thickness 150μm - 316 Stainless Steel

Helps keep the Group Head clean. You may have seen discussions about puck screen benefits like preventing puck expansion, promoting more even water distribution, improving consistency, drier pucks, cleaner baskets...but what I like most is that it seems to do very well at keeping the shower screen clean. Some people seem to be just magically neat and clean. Not me. I make messes, sometimes big ones and I seem to get coffee grounds everywhere no matter how hard I try to keep them contained. Never made espresso on my new Breville without a puck screen except once when I forgot. After every use I wipe the shower screen and around it (the best I can) with a paper towel and the only time I got more than a VERY minute amount of coffee color on my paper towel was after the time I forgot to use this Normcore puck screen. Almost every time the paper towel is spotless and when it's not it is always up in the group head around the shower screen, I'm guessing from grounds I missed and didn't wipe from the rim of the portafilter. Bottom line, the only cons I have seen for puck screens are that you have to pay for them and clean them. This is a good one and I don't mind cleaning it.

great product; keeps espresso machine clean... durable and easy to wash. fits great.

Works great with our breville! Great quality and helps pour a perfect shot

It works! The flow of water is more homogeneous, and "cream" is much richer.But make sure that the puck temperature is equalized with the portafilter to avoid temperature reduction when water passes through the holes.

Once I purchased puck screens for my espresso, I suddenly found that I also needed something to hold them without destroying them. After some research I found a large number of similar holders available that not only ranged in size and shape, but also price. Narrowing it down to getting a holder that comes with a name brand attached, these holders were workable. Nothing fancy. Nothing ornate. And well within the acceptable price range. Meaning, it fit on the counter without taking up too much space and at a reasonable cost. It will hold screens up to 58.5mm, which for me, works out well. Durability? That remains to be seen. As the materials used are rubber, they have a tendency to rip, stretch, or both. So, for me, time will tell. If you are looking for something small to hold your screens, will do the job, and clean up well, then by all means these are the ones to look into. If you are looking for fancy? Keep looking. If you are looking for simple and a reputable backing? These will serve well.

What a great product.The difference in my used pucks when I use this and when I do not is remarkable. They are tighter, more compact 100% soaked through evenly and I’ve never ever had any channeling.I’m using this with a rancilio rocky and a gaggia classic eco pro at home. And at my work we have a rancilio Silvia and a rancilio md40 grinder.Dame results at both places.Biggest bonus is how clean the group head stays.These are one of the best things you can buy if you’re making espresso. Period.

Good quality and does exactly what it needs to do. Shot quality has been great since m

My first thought was ‘oh great, another gimmick for espresso nerds.’ But having used this little ‘puck screen’ for a few months now, I’m convinced it’s a useful tool… not indispensable, but definitely a nice addition to my shot-making process.The huge plus: it separates your puck from the shower screen on your E-61 grouphead. As a result, you won’t need to pull the gasket and screen every day or two to remove coffee residue from the screen and to clear the groove around the inside edge of the head. It will stay clean as a whistle. This also reduces the need to backflush your machine with a cleaner like cafiza, which chips away at the lubricants on the valves and cam inside the group. That means less grouphead maintenance as well.As for improved extraction and less channeling, I can’t vouch for that one way or the other in a scientific way. However, I do find it is a bit easier to dial in my tamp, grind and dose; I seem to pull more consistent shots; and the spent pucks are more uniform and uniformly saturated when I dump them.My two issues/concerns about using this are readily addressed.First, I dropped my typical 19 gram dose to 18 grams to avoid ‘overstuffing’ my portafilter and making it difficult to cinch down to 6 o’clock on my ECM machine.Second, I worried that this would draw heat from the brewing water and the basket, resulting in an underextracted shot. The simple solution is two-fold: A) I fill my 5 ounce cup with boiling water and drop the puck screen in while I’m grinding beans and packing the portafilter basket. Then I dump the cup, put the hot screen atop my tamped coffee (careful of those fingers!) and proceed. B) I do a longer preinfusion to ensure the coffee is amply saturated before I begin extraction at 9.5 bar. I shoot for a 1:2 coffee to espresso ratio and extraction around 30 - 32 seconds with most medium roast beans.All in all, this has been a real value proposition for the $20 investment. Recommended, if you’re willing to expend a little extra effort making your espresso.
