Normcore58mm Magnetic Dosing Funnel V2 - Espresso Coffee Dosing Ring - 18mm Anodized Aluminum with 9 magnetized Steel Compatible with 58mm Portafilter

I was not thrilled to pay over $20 (on sale) for a dosing funnel, but honestly it's really nice. Firstly, it fits very snugly on a 51mm Delonghi portafilter. It does not wiggle around much or leave gaps thanks to the magnets - so no grounds collect under the funnel. Its shape is good - the top of the funnel flares out so that it catches more grounds (compared to my old one which was just a straight-sided open cone). It's just an aluminum circle, but it is well made and designed. Honestly, it is a huge improvement over my last funnel, so I'd say it's worth the price.

Works as advertised and is a nice size. Magnets are strong enough to hold but not too strong that you have to fight to get it off the portafilter

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

I have two of these for two different places. One definitely has stronger magnets than the other so is a bit more likely to fly off if you shake your portafilter too much. Regardless, it does what is needed.

Well built, strong magnetic grip helps contain espresso grinds. Easy to use.

After researching and reading reviews, I bought both heights of this to try out. To be clear, both fit my crema portafilter perfectly and neither fit in the cradle of my Breville Smart Grinder Pro (which I knew going in and isn’t a big deal at all). I was personally able to get the right dose with the regular height and it fit the distributor/tamper combo better than the tall. I know I could adjust the height of the distributor but was lazy. I didn’t need the height of the tall one so returned that one. I am VERY happy with the regular height. The magnet is perfect and makes using WDT so much less messy. It really has added such ease to my routine.

Solid, fits, works, decent price, would buy again (although I don't think I'd ever need to unless I lose it).

Perfect fit on 54mm Breville, strong magnets, nice wide flare that easily catches grounds with minimal mess.
