> We like them because you can make one or two cups without wasting a lot of coffee or water. So just like a regular espresso machine. You put espresso powder for one or two cups in the portafilter, put some water in the tank, done. Tank doesn't need to be filled completely, but you can just keep the water in there for the next espresso. No waste created, and you can even reuse the powder as fertilizer.
