Nice basket. Extraction is more even, and seems to make other variables a bit more forgiving
Just for info, the IMS Precision Filter Basket 16-20g Ridgeless I bought from COFFEE HIT fits the Rancilio Silvia portafilter and is better than the one supplied with the machine.\n\nThe CompetitionE61RidgelessDoubleFilterBasketbyIMS28.5h1822Gram\n as recommended by another coffee supplier DOESN'T!
