KYONANO Espresso Accessories - 51mm Magnetic Dosing Funnel, Espresso Coffee Dosing Ring, Compatible with 51mm Delonghi & EUPA Portafilter Series, Espresso Accessories for Barista, Home, Cafe

This dosing funnel fits my Delonghi 51 mm 2 tab/ear portafilter perfectly. I have tried it on the original portafilter that came with my ECP3630 as well as a bottomless portafilter and it works for both. I originally bought a funnel that had a portion of the funnel extending inside the portafilter creating a thin moat around the edge of coffee, the Kyonano sits on the lip of the portafilter so no more moat. Was concerned about the fit before I bought it as this Delonghi portafilter has the tabs almost flush with the top of the portafilter and I read reviews of other funnels that allowed grinds to leak through between the bottom of the funnel and the portafilter requiring filing down the funnel rim at the portafilter tabs to fit well, it wasn’t needed with the Kyonano. I like that the funnel flares to minimize spillage. Nice looking diamond pattern on the exterior.

I would say that this product kind of works, but not really. When compared to other products at a higher price point we can see a clear difference. First, this product has weak magnets that don't actually hold it in place on my portafilter. Second, it just doesn't feel as premium as a more expensive dosing funnel would. That being said it does do it's job which is why I'm giving it the three star review. While the magnets are weak it helps keep my espresso grounds from flying all over the table.

It fits well and does the job but as another reviewer mentioned, the magnets are not strong so be careful when shaking the grinds. Not sure how long magnets will work.

The build quality is good but the magnet is very weak, can't even stand on place if you gently shake

I have an Delonghi espresso machine that uses a 51mm portafilter. I needed a dosing funnel to contain espresso grounds while packing. This dosing funnel does the job perfectly. It magnetizes to the portafilter to hold it steady. I would say the magnets are not incredibly strong so it can wiggle a bit. However, I think it still does the job effectively. It also has a very nice look to it and looks like it's made from quality materials.
