Simple, high-quality solution that makes the transition from grinding to tamping much cleaner!
Color: Black, Size: 58mm, Color: Black, Size: 58mm
I wanted to streamline our espresso workflow. I added the Normcore Magnetic Dosing Funnel V2 to our kit because loading up the portafilter & using the WDT was causing a mess on the counter. This funnel stays put and looks great. is it required? No. Does it work great? Yes!
The Good: What Works Well
Rock-solid attachment: The magnets are impressively strong. It snaps onto the portafilter and doesn't budge.
WDT’s Best Friend: It provides the necessary height to use a WDT tool without making a mess.
Low Profile: Unlike some "tall" funnels, this one is compact enough to fit under many grinder dispensers while still attached to the portafilter.
Premium Finish: The matte black anodized aluminum feels incredibly durable and matches high-end espresso gear perfectly.
The Not-So-Good:
Price Point: It is definitely a premium option. You can find plastic versions for less, but they won't have the same weight or magnetic security.
Pro Tips:
Maintenance: This is anodized metal; do not put it in the dishwasher. Just wipe it with a dry cloth or a dedicated coffee brush.
Magnet Care: Keep the bottom magnets clean. If coffee oils or grounds build up on the magnets, the "snap" won't feel as secure.
Compatibility: Make sure you pick the right size!

Reduces Mess, Lightweight, Strong Magnets, Fit is OK
Color: Black, Size: 58mm
I've been stubborn about buying a funnel - yet another coffee tool to simplify and optimize, right?
But, it really does reduce the mess when using the WDT tool.
The magnets are quite good, a different brand funnel (with magnets) wouldn't even stick to my portafilter.
The fit is OK - it does slide around on my 58mm basket if I move the funnel. But, that hasn't been an issue because the magnets keep it in place.
The shape is also a bit more tasteful than most of the generic funnels.
Oh, and beware - if you're grinding directly into your portafilter basket (hands-free), the funnel may not fit into your grinder's portafilter-holder. This was the case with my DF54 grinder.
Overall, I'd say it was worth the extra ~$4 USD over generic competitors.

Great coffee dosing funnel
Color: Silver, Size: 58mm
Normcore products seem to all be high quality. This funnel works very well. Strong magnets hold it securely to the portafilter. My only small complaint is I wish it was just slightly taller on this 58mm version. Just a few millimeters of additional side height would be a great advantage at times when the fine ground coffee decides to come out of the dosing cup in a clump. This current model still makes it much better than with no funnel and does the job quite well.

Very nice funnel
Color: Black, Size: 58mm
58mm fits perfect on a Pullman basket. Good quality as well. Be careful the magnets are strong the benefit of this design though is, it is a tamp through. Keeps the mess to a minimum transferring from dosing cup to portafilter, keeps your grounds in the basket during distribution as well.

makes it easy to pour into and wdt your portafilter without making a mess
Color: Black, Size: 51mm
Did you know there are 2 different types of dosing funnels, one with a inner collar/lip and one with an outer one?
the normcore dosing funnel has an outer collar/lip, which means it secures to the outside of the portafilter basket, keeping it lined up. i didn't realize when i bought it, but the advantages to the outer lip is that there is no space or gap when the dosing funnel is removed (the inner lip takes up space along the edge of the basket, leaving a ring of space without coffee grounds). having the lip on the outside means, when you're done with your wdt, you don't have to do anything else besides tamp.
at first, i was getting grounds all over the place when i was tamping because the grounds would push out to the sides as i was pushing down. i realized that the tamp (normcore v4 tamper) fit perfectly in the dosing funnel, so before i removed the funnel, i would lightly tamp with the tamper, giving me a little more space to place the tamper without worrying about grounds going all over the place.
the magnets on this dosing funnel work pretty well, although, depending on your basket, it may work better than others. when magnetically attaching the funnel to different baskets, flipping the funnel upside down and shaking, holding the basket, the dosing funnel held pretty securely to the pressurized baskets that came w/ my delonghi, as well as the basket that came with my bottomless portafilter. the ims precision competition basket however, doesn't hold as securely.
i thought at first it was because the lip of the basket was too big, but it turns out it's the same size as everything else. it turns out that while most of the top of the basket is flat, the inner edge is raised, maybe to help keep grounds from coming out. that raised bump on the top of the basket, is taller than the other baskets, so the metal that is to come in contact with the magnet is further away compared to the other baskets. still, it holds it securely enough while using it normally, so i won't be doing any modifications to the ims basket.
the normcore also flares out at the top, making it wider. this helps with wdt-ing, allowing to work at more angles compared to the straight walled versions. it also makes pouring your grounds into the basket easier.
although a little more expensive compared to other dosing funnels, i am very satisfied with how it makes it easy to wdt and tamp without making a mess. there was a little learning curve/trial and error to find the best way to use it, but i figured it out on day 2.
would definitely consider buying another if i get a different machine with a different portafilter size
