Quick verdict

A dosing funnel sits on top of the portafilter so grounds don't spill while you dose and stir. Normcore's 54 mm V2 is 18 mm tall, anodized aluminum with eight neodymium magnets, and Normcore lists fit for the Barista Express, Barista Pro and Bambino Plus. Normcore also notes it can't be used while the portafilter sits in the built-in grinder cradle of machines like the Barista Express. It suits Breville 54 mm owners using a separate grinder, or dosing away from the cradle.

Buy it if

  • You grind into a 54 mm portafilter with a separate grinder, especially if you use WDT.

Skip it if

  • You grind in the Barista Express's cradle and won't move the portafilter.
Best for
Breville 54 mm owners grinding with a separate grinder, especially with WDT.

Strengths and limitations

What stands out

  • Magnetic hold with eight magnets (Normcore).
  • 18 mm height keeps the funnel low.

Limitations

  • Won't fit in built-in grinder cradles, per Normcore.
  • Hand wash only.

Our recommendation

I'd recommend it to Breville 54 mm owners using a separate grinder and WDT.
