I checked with the company before ordering to make sure the portafilter was the correct fit for my Gaggia machine. When I received it, it seemed to fit fine but when I started to pull my espresso it sprayed out from the top side 3 ft across my kitchen and into my cupboards! I am waiting for the company to give me my money back which they haven’t even said tat they would. I am still in contact with them but no solution yet.
