51mm Magnetic Dosing Funnel, Espresso Dosing Ring, 18mm Anodized Aluminum with 8 Neodymium Magnets Compatible with 51mm Delonghi Decica Portafilter, Black

We recently added the Normcore 51mm Magnetic Dosing Funnel to our espresso setup, and it’s been a game-changer for improving workflow and reducing mess during dosing and distribution. The build quality is excellent, solid, well-machined, and feels premium in hand. The magnetic attachment is strong and secure, snapping onto the portafilter with satisfying precision. However, unfortunately, the funnel did not perfectly fit our portafilter, leaving some gaps in-between, so few coffee grinds slips through. We use the funnel in combination with our WDT tool and tamper, it makes my routine more engaging and fun. One of the standout features is how much cleaner and more consistent our dosing process has become. The sleek, matte finish also complements the rest of our espresso gear nicely. Cleaning is effortless—just a quick rinse or wipe, and it’s good to go. The compact design makes it easy to store, and it doesn’t take up unnecessary space on the counter. For its quality, no doubt it's a good value for money, but not cheap at all.

Great dosing funnel. Sits tight and the magnets are strong

This works like it should. Some reviews say the magnet is weak. I disagree as the magnets hold everything in place. This maybe because my handle and filter are all the same brand. Great product can't fault it

My dosing cup is a lot smaller than my Gaggio Classic Pro (58mm box standard, with original basket) portafilter, this is a great tool to disperse freshly ground coffee from my Normcore V2 hand grinder to the portafilter without a mess, especially if you fluff/WDT as part of your process. This is a bit on the expensive side but Normcore is a brand I trust and contrary to some of the reviews here, I can confirm the magnet is strong and doesn't move around (at least for me). I can manage to WDT and tamp with this funnel ring on.

Amazing product but expensive. I can tamper with this on the portafilter so there's no coffee ground leakage. However it's really expensive fir what it is.

Older reviews make it clear that previous versions of this item had trouble with the magnets being too weak. I can confirm the version I received had magnets strong enough to secure the funnel to the portafilter while being weak enough that I didn't accidentally lift my ridgeless basket. Aside from this, the tolerances mean that it wiggles around a bit on the portafilter but I haven't found any way in which this impacts its utility. I specifically bought this so I could use a WDT tool without spilling coffee outside the basket and it performs this task very well.

Arrived yesterday and made my first two mess free espressos today. Have a Gaggia Classic Pro with the 58mm portafilter that comes with it and this fits really well on the outside of the 'cup' so no intrusion into the coffee. Magnets easily clamp it into place and strong enough to hold it firmly in place but not so firmly you can not get them apart. If the magnets were any stronger then that may be an issue. It's black, looks smart with my set up. Good value for money and does the job perfectly.

Good build quality, attaches easily and helps prevent coffee spillage when using a WDT tool. Would recommend.

I wasn't sure about this dosing funnel since I'd seen several reviews saying the magnets weren't strong enough or that it wore out. I've been using it for a couple of months now without one single issue. The magnets snap on pretty easily and are strong enough to keep the funnel secured to the portafilter upside down (not that you'd need to hold to PF upside down). That being said, it can easily be removed if needed. I've tried weighted dosing funnels before and those were a bit finicky--they were heavy but somehow still easy to knock off accidentally and ruin a good puck. I recommend this one over the other style. Normcore has yet to disappoint: I've been using their portafilter, basket (I think?), puck screen and this funnel for months with not one single issue. I highly recommend this dosing funnel and their other products as well.

Not the best design, but the most effective magnetic dosing funnel because the used good magnets. I'd prefer it to be taller and wider, but it still works extremely well. Very stable due to the strong magnets and won't just fall off. Easy to use. Perfect fit and compatible on all my 51mm portafilters.

Attached seamlessly to the group. Does its job. Recommended!!

Facilito mucho mi proceso para crear espresso, ya que antes batallaba mucho para poner todo el cafe que necesitaba en la canasta del portafiltro, y por mas que tratada de tener mucho cuidado, solia perder un poco de cafe en este proceso pero con este dosificador eso ya es historia. Lo estuve utilizando tanto con el portafiltro que viene en la Delonghi Stilosa como con el Normcore y lo que les puedo decir es que en ambos lo hace bien, sin embargo, noto que es ligeramente mejor con el portafiltro Normcore.

デディカデュオで使用したが、マグネットがしっかりしており、コーヒー粉があふれ出ずタンピングしやすく調整でき購入してよかった。
