Normcore 58mm Espresso Dosing Funnel V2 - Magnetic Dosing Ring - 18mm Anodized Aluminum with 8 Neodymium Compatible with 58mm Bottomless Portafilter - Non-stick coating White (58mm V2)

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

Does the job very well

I bought this magnetic dosing funnel because using the plastic ROK one, I've occasionally accidentally knocked it off the portafilter and made a mess with the coffee grinds. This has so far eliminated this issue.

It's way too expensive for what it does, but had to buy it because it's the only tall funnel on the market that sits on the portafilter without touching the coffee.I use it on a 54mm portafilter and it works great with the 58mm ESPCUP, or a 58mm generic blind shaker, sitting on top of it.The magnets seem to be working, but not that good on the IMS baskets.

I procrastinated about getting one of these for my Normcore bottomless portafilter but after getting fed up with spillage and wiping up, I just bought it. There are some gentle magnets that clip it securely in place above the 51mm Normcore portafilter which allows easy filling of ground coffee without worrying about overspill. You can also tamp with it in place too. You’ll soon forget the price once you’ve used it.

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.

Good quality and fits a 54mm portafilter nicely, but it is let down by very weak magnets that do not keep it safely in place. I have a shallower one and the magnets are a lot stronger, I’m not sure why the same magnets have not been used on this version. Shame because it could have been a great item.
