A magnetic dosing funnel that sits on 58 mm portafilters to keep grounds inside the basket while you grind and distribute. Magnets hold it in place, and a wide opening leaves room to work with a distribution tool or WDT needle. It lifts straight off before extraction. Compared with funnel-and-cup combos, it is a simple ring with no dosing cup or dosing collar, so it suits people who grind straight into the portafilter. Owners rate it highly for fit and cleanliness, though some note grounds can cling to the sides.

Buyers rate it 4.7 out of 5 and mostly praise the magnet grip and the tidier prep. Complaints center on grounds sticking to the sides and the 58 mm-only fit.
The Magnetic Dosing Funnel is made for 58 mm espresso portafilters. It keeps coffee grounds inside the basket during grinding and distribution. A wide opening gives room to work and stops grounds from spilling over the edge of the portafilter, which supports cleaner puck prep.
Magnets hold the funnel firmly in place on the portafilter, so it stays put as you grind, distribute, and prep. When you are ready to brew, lift it off.
