Works well, measurement markings holding up
Color: 01_ Silver 1pc
This is a nice espresso shot cup. It's wide enough to catch both espresso streams coming down from the portafilter. I really like the measurement markings on the inside. I was concerned when I bought it that the markings might come off over time. I've had it for several months, and so far the marking are holding up well even when run through the dishwasher.

Efficient
Color: 01_ Silver 1pc
This cup holds two shots and then some. It fits perfectly under to catch the espresso. The material is durable and it’s easy to clean. I recommend this!

Does what it's supposed to do

Works well for a double espresso. Small but large enough to fit under two spouts.

Good quality for small amounts of espresso
Color: 02_ Black 1pc
So truth be told I dont even use it because I actually needed something that held a lot more than what this holds but it is really nice.
