Making nice coffee at home

R. has provided and instructed me in a little espresso maker. One fills the lower chamber with water that one then heats. The water rises through pipes then a layer of coffee before appearing in the upper chamber. I have no idea what coffee aficionados think of it in comparison with, say, the AeroPress® or Breaking Bad's Gabe's thinking, but I rather like the coffee that this device makes me from the Sang Tao 5 from a local Vietnamese grocery store; next I shall try their number 1.
