Coffee Accessories Dosing Ring

magnet came loose

magnets work well for the dosing ring to attach on. Only issue with it is that one of the four magnets did get dislodged for me. the other 3 units are still in their respective slots.

Cleaner process, can cause channelling

Does the job, but as someone noted here, it creates a channel around the porterfiller inner rim, so you need to be careful and tamper to compensate.

Works well, great design and finishing but the magnets are extremely weak
