Puck Screen 53.5mm Reusable Puck Screen for Espresso Portafilter, 1.7mm Thickness 150μm 316 Stainless Steel Screen Filter Basket Compatible with Espresso Machine

This screen helps with water distribution and keeping the machine head clean. Not sure I noticed a change in espresso flavor but this is a worthwhile accessory.

Working good

Love it, does what it is supposed to do plus cute coffee written on it love it such good quality thank you

Didn't fit my espresso handle even thi I chose the right dimensions

This fits on my Breville Bambino plus portafilter pretty well, I usually have to push it down a bit to get a flush fit. Fine grounds seem to get stuck in the material as well.

I like how it helps keep the machine screen clean while also providing an even layer for the expresso grinds.

This screen is similar to most other screens I've used. It's relatively inexpensive and it definitely does something. It added around 3-5 seconds to my extraction time, but your mileage may vary. I purposely made my puck prep worse to see if noticeable channeling would occur. I saw very little channeling with the screen on. Took the screen off, channeling. So yeah, at $6 it's worth a shot if you want to fix bad or inconsistent puck prep.

Does exactly what it should, which all you can ask of a product. It lets water though while protecting your espresso machine from the wet grounds.
