Query: Not an espresso maker ...

While I'm sure this coffee machine can make OK "strong coffee", it is not an espresso machine. Water is forced through ground coffee using steam pressure (little over 1 bar of pressure), same principle as those italian stovetop coffee makers. It is well known that 8 to 10 bars af pressure are necessary for full extraction of the coffee oils that make espresso. You'll need a machine with a pump if your intention is to make true espresso. I'd get the italian stovetop coffee maker instead of this one : works better, easier to clean and will last forever. I suggest the one made out of steel, not aluminum. ciao.
