51mm Bottomless Portafilter Compatible with CASABREWS CM5418, 3700Essential, Mr. Coffee Espresso and Cappuccino Machine, Wirsh Espresso Maker | 51mm portafilter 3 ears with Prongs Thickness 4mm

It fits my Mattinata like a glove! No leaks or spurts... finally!Quick backstory:I was gifted an espresso maker by the brand Mattinata, which is nearly a copy of the CasaBrews machine. I got a fancy Normcore basket, but it didn’t fit the portafilter that came with my machine. So began my journey to find a portafilter that actually fit both the basket and my machine—not an easy task.Overview:I noticed a significant difference in the sheen of my Normcore basket compared to the metal of the portafilter from my original machine. This portafilter, however, matches the same level of sheen and quality. It was the cheapest 51mm 3-prong portafilter I found that explicitly stated the prong thickness. While my priority was functionality, I was thrilled that it also looks great, especially for the price.It fits snugly. I have to use a little extra muscle compared to the old one, but it doesn’t feel overly tight. Instead, it gives the sense of a better seal.-Overall:If you need a bottomless portafilter for your 51mm budget-friendly espresso maker, this is the one you’re looking for.-CAPFEI, if you’re reading this...Please make this same style portafilter in a version that can lay flat. My only minor gripe is that it wobbles unless I’m holding it while filling or placing a rag underneath.

I have bought about 3 different bottomless portafilters for my Casabrews CM5418 espresso machine and none of them worked. Before buying this one I was skeptical of some reviews saying this one actually fit but IT DOES!Comes with a basket that produces 2 shots of espresso and it fits like a glove. I just pulled my first shot of espresso from it and it came out beautiful and tasted better than ever!If you buy this and are experiencing coffee spewing/leaking everywhere try checking the size of espresso grind or the amount of espresso packed into the portafilter.I am in love with it and could not be happier! The quality of it is immaculate and for the price that it is, it’s a steal! Super easy to clean and it makes the espresso-making experience 1000x better! 100% recommend!

I bought this portafilter as a replacement for the pressurized one that came with my Gevi 20-bar espresso machine. The original portafilter had plastic spouts, which I wasn't a fan of. I'm so glad I found this compatible option. It's a much better fit for my preferences and feels like an upgrade in both quality and performance!

Fits fine on my gevi espresso but leaks coffee everywhere

Works well but not as much crema as a pressurized filter.

The 51mm 3ear fits my spacekey espresso maker perfect. There are 2 things to help avoid problems that took a little while to work out, mostly not caused by this basket, but that the basket brought out in other tools I was using.1. Use a 51mm paper at the bottom, this absorbs the cafestrol and also stops the shooting sideways streams when overtamped or too much pressure. A puck screen on top seemed to make it shoot out too fast.2. My cuisinart grinder has 18 fine-ness settings, even the finest was not fine enough. Different doses/grinds/tamping/grind distribution tools did not seem to help. If you make espresso from an inexpensive espresso machine like myself, (and it seems to always come out super watery with this basket), then try getting the espresso powder from a budget german grocery chain that comes in a vacuum sealed cube pre-ground. That stuff is even finer than my grinder, and once I tried with that I got the correct crema and pressure from my machine. Now I just need to get a better grinder or find decaf peurto-rican coffee. The hint this was the case is all my beans made great pour over, so I didn't think it was them, and the pressurized basket that came with my machine seemed to make ok espresso if super packed in there, and a large number of attempts at diffent coffee masses/grind size did not help get any crema. See attached comparison, it should be super super fine. Both powders work with pressurized portafilter that originally came with my machine, but the super super fine one works best with this one.The puck also comes out way better than the pressurized basket making it easy to clean. The box art had a 2-ear printed on the front, but the inside matched perfectly to what I ordered.

The media could not be loaded. I have an Amaste espresso machine. I have not been able to find ANY replacement parts or accessories for it.The portafilter my machine came with was fine, but it only has dual-wall filters (fine for beginners, but zero learning is done). This portafilter fits the machine perfectly AND the single-wall filter basket can hold a few extra grams of coffee which is a delight!As for reviews mentioning spillage/leaking, there are a couple important things to note: 1. Bottomless portafilter are heavily known to leak/spurt if the puck isn't perfect (channeling, wrong grind size, etc), so this is due to learning and user error. 2. Always ensure this is locked tight on the group head so there's nowhere to leak.As mentioned in other reviews, ensure the handle is screwed on tightly before each use so it can't fall off!Overall, great for the price point and I'm thrilled it works for an Amaste machine!!!
