Product is amazing and works better than I thought it would. Magnets are strong and stay put while I tap the portafilter lightly on my tamp mat. This product was the best solution to keeping my espresso station clean from loose grounds.

Coffee Espresso Magnetic 51/52/53/54 MM Dosing Funnels> Barista Space

What can I say? Light, solid and well made construction, and the magnets are just right

Very happy with the dosing ring, magnets are excellent and more than strong enough to be able to tap the bed flat and use any distribution tools. Because the rings fits multiple size baskets it may not be perfect on smaller sizes, but it’s very good on 54mm ims baskets I use

The design of this dozing ring is genius! The magnetic attachment is strong and the ring attaches to the outer rim not the inner rim, which makes a huge difference in making a nice surface for a great tamp.
I very much recommend this if you are thinking of a dozing ring or funnel.
