Normcore58mm Magnetic Dosing Funnel V2, Espresso Coffee Dosing Ring, 28mm Anodized Aluminum with 8 Neodymium Magnets Fits 58mm Breville Portafilter

So its a funnel for your portafilter basket. It fits well, it funnels grinds, and keeps you counter a bit cleaner. I think the only downside about this is the price. Honestly I would have been perfectly happy with a bit of high-grade molded plastic (like the stuff power tools are made of) set with magnets since its all about function. But this is machined aluminum which is then anodized, so that is what you are paying for.That said it works.First the shape. The groove on the bottom sits OUTSIDE the lip of the portafilter basket so you have full access to DE clump the sides of the basket, and you can tamp with this in place. And its sized accurately for the 58mm basket I use.Been using it about a week and so far the magnets are staying in place. The extra magnets seem to give it a tight fit, it will hold up even if you turn the portafilter upside down, but not too tight so its annoying to remove. Your mileage will very depending on how ferrous your basket is. For example, one of my baskets, magnets don't seem to stick it because of the alloy its made from.I got the tall because I use a Baratza grinder so clearance isn't an issue for me. Gives me lots of room do do the WDT thing to break up clumps with clumsy abandon. Very good for morning coffee when you are not awake enough to be coordinated.The only problem I have is price. I know people who do machining for a living. I realize the margin I had to pay for this is kind of insane. (Think 10x) But all the competition apparently failed at being about 1oz of turned lathe turned metal sized to the nearest 0.05 of in inch, which is so pathetic its impressive. But its also a lunk of turned metal, so it *should* be a buy it for life kind of thing. I theory I could break this, but I would have to actually put effort in. Even the worst case, if a magnet comes out, epoxy will fix that in a minute.

It comes with multiple oblong shaped magnets. They're not super strong but as a whole, it is strong enough to stick to the basket upside down.It's easy to use and easy to keep it clean. Works well with IMS Competizione basket. I like the color too!

Works great with the stock breville basket setup. Goldilocks magnet strength makes it easy to use. No gaps at the filter basket. Fits well. Good build quality. A necessary accessory; a good buy.

I like this item very much.Do beware that some filter baskets are not magnetic, and this item won't work with them.Worse yet, such filter baskets do not mention that they are not magnetic. Ask before you buy.

Good quality. Sits on the edge of my 58.5mm E61 portafilter handle and stays put with the included magnets, and I can easily tamp through it. I've been more into dosing cups lately because of my specific grinder, but if you like to grind directly into the portafilter this is an excellent funnel for that.

Since it wasn't explicitly mentioned elsewhere, the 58mm Normcore dosing funnel fits the Rancilio Silvia filter basket* just fine. The magnets are strong enough to stay in place well enough to do your grind dispersion, but not strong enough to pick your filter basket up by the funnel (which is good, that would be too strong of a connection).Funnels like this not only make grind distribution easy, but you get the added benefit of not losing any beans during the process of grinding into the filter basket.Great addition to the espresso kit!* This was tested with the Rancilio portafilter part number 20-12-210 and filter basket part number 40-100-010 which is the double-shot (17g) basket.

Works like a charm. Fits the basket well. I recommend!

It fits the portafilter well, but the magnets aren’t super strong. You really need to hold it in place and be careful not to bump it or you’ll have grounds all over the place.While it will hold on upside down if you’re dosing from a cup with a flip up right, it’s easily dislodged.
