What is the opinion of Reddit about the
DELONGHI ECO310BK Espresso Machine, 10.2 x 9.1 x 11.8 inches, Black/Stainless?

This little lever/part on the portafilter is almost like a clamp…it’s a delonghi specifically this one: https://www.amazon.com/DeLonghi-ECO310BK-15-Bar-Pump-Espresso-Machine/dp/B002Q0EE4U

When you look at part 29 on the diagram for the ECO310Bk on google, it’s either called a lever or a sump. Sorry, that doesn’t mean much to me. WITT
