“Cheaply made--I'm disappointed. The glass has bubbles in it. The pour spouts are small and uneven (the picture is misleading). It pours from the front OK, but a side pour dribbles. It's barely wide enough to catch both sides of a standard portafilter. It suffices for the time being, but I'll probably get something else.”
“These are amazingly strong glass, they last a long time and are extremely useful when making shots of espresso. It also ensures that all of our shots are the right measurement every time.”
