MacMaxe Portafilter Bottomless for La Spaziale Espresso Machines

This is an great portafilter for the La Spaziale group heads @ 53mm

Decent portafilter purchased for a S1 Vivaldi. Fitment wise, it's not perfect. I have experienced small drips overflowing on the handle side on occasion. Estimating about 5 times in 25 shots pulled so far. Maybe it needed to be broken in. My Vivaldi was had its washer replaced, and my stock portafilter doesn't behave this way.Handle is glossy plastic, did came loose, but easily re-tightened.
