MHW-3BOMBER 58.5mm Espresso Puck Screen with Round Hole Metal Espresso Filter 0.8mm Thickness Coffee Filter for La Marzocco/Gaggia FG5586

Purchased this, and the black titanium coated version, they both arrived 23 days ago. Using these both and alternating between the two to pull 3-6 shots daily total I hadn’t noticed much of a difference. They feel nice not too heavy or light, fit in the portafilter well, clean up easily, and keep my head clean. All in all, works just fine. As of this morning, the screen is beginning to split from the other side as it’s just stuck together. This allows a bit of ground to make its way between the screen and holed part. Without damaging further, it is quite difficult to clean. Unfortunate, as I was a big fan of these to begin with. The titanium coated version has seen a bit more use, and seems to be holding up just fine. When in proper working order, they do a great job of keeping the head clean, and come out of the portafilter very easily. EDIT: Original review 2 stars as the portafilter screen split as seen in the photo. Seller contacted immediately with options to correct the situation. Was prompt, and friendly. Great customer service, will absolutely order from them again.

As my title states this is my go to screen. I too fell onto the screen bandwagon and doing my own Coffee beans for many years roasting my favorite single origin, so I know enough about coffee and espresso to be dangerous. With my double boiler machine, one thing that always bothered me , is sometimes it could channel no matter how careful I was with grind tamping and all those other finesse things that we get trapped into. There are lots of opinions on why this occurs, and I have explored them over the years , but I have found a screen, pretty much eliminates any of my channeling problems. So now it came down to just a matter of thickness and mesh size . After quite a bit of testing this disc has become my absolute favorite. A great balance between being overly thick and taking up too much space or being so thin that it becomes flimsy and you get some grind splashing up around the edges. Turns out this is like the baby bear says , just right. I now have no more channeling , clean up is faster. My water screen doesn’t get dirty , nothing but positives. The last picture shows the three screens that I’ve been trying different styles different thicknesses so as you can see, I’ve been through a little bit of testing.

It keeps the brew head COMPLETELY clean. I think it helps with channeling as I am only using 7 g in a 7 g basket. Get a holder with a magnet to extract it from the basket after using.

Perfect fit for the portafilter of my Breville Bambino. The design of the holes is much easier to clean compared to other styles. I mostly use it because it makes keeping the machine much easier, I'm not convinced whether or not it actually impacts extraction.

Not a coffee game changer, but here are the benefits: 1) Cleaner operation of group head over multiple shots 2) An extra layer of dispersion to avoid channeling incrementally Negatives: 1) Knocking out requires two steps - knock gently to remove disc, knock hard to remove puck - if you don’t like touching not for you 2) On finicky beans that require a very even distribution and acceptance of water from the group head will actually reduce flow and cause over extraction. So you have to know which beans and grind benefit and don’t from using the disc OR you need to recalibrate grind and pressure for using disc with that finicky bean extraction Overall Better than other screens/discs I have used due to thinness and difference in the two sides. Knowing when and how to use optimizes. Not as big a deal if you dial in on one bean and grind.

This screen is pretty awesome for a few reasons. A: It’s supposedly thinner than your average mesh screen, which is great because I’m already pulling a triple shot, so I don’t have room for a deeper basket without switching to a blind portafilter—cool looking, sure, but also a bit of a mess to deal with. B: It’s super easy to clean. I can confidently say no sneaky coffee grounds are hiding in the pores, unlike other screens where you need to launch an excavation mission just to feel like it’s clean again. C: The biggest win? It keeps those sneaky coffee grounds from launching themselves back into my machine, which is a good thing for anyone who cares about keeping their gear spotless. One of the photos shows how it keeps my shower screen nice and clean! Now, does it make a huge difference in extraction quality? I like to think so, but the design is curious with how spread out the holes are. One important tip: make sure the bigger holes are facing up! If they’re down, the espresso gets stuck in them, which is way less fun than it sounds. At the end of the day, it's more about keeping my machine cleaner and adding an extra gadget to the espresso ritual. Because let’s be honest, the more toys involved, the more fun it is!

Perfect puck screen for my Gaggia espresso machine. I would definitely recommend and will buy more in the future. It’s a plus for the price too!

Not too thick, fits great, works great

I think this made my coffee better. Just remember to take it out of your compost bin when u knock it out of your portafilter. A few times I forgot and had to dig in my city bins for it.

Good but expensive

Macht was es soll fuckt aber ab das immer sauber zu machen. Ist auch sehr Nasty zu sehen was passiert wenn man den ins Ultraschallbad legt

Works really well (on a Gaggia Classic Pro), giving even consistent water flow and keeping the shower screen nice and clean. It does have a right and wrong orientation to watch out for- the holes should be upwards, with the mesh on the ground coffee. It’s thin enough that it doesn’t impact the screw with a full dose in the basket, and is easy to clean. Would recommend.
