Review on 🔧 Convenient Hands-Free Dosing: MATOW 54mm Funnel with Grinder Trigger for Breville Portafilters by Andrea Joint

I used one of these 3D prints from Etsy until it went in the dishwasher and the plastic warped. This works even better than the 3D printed one, the notch that toggles the Breville grinder to auto duration works perfectly. (The 3D print was too long and it was difficult to do the automatic grinding compared to manual grinding.) We recently received a second grinding machine, also from Breville. It doesn't fit in the portafilter holder, but on this model the portafilter holder is held in place with magnets (allowing different size portafilters to be fitted). So it's no problem to pull out the portafilter holder, hold it yourself and press the start button.
