First, what a fantastic machine.  2nd, it's a bit complicated, so you'll need to take your time in getting to know it.  I'm still working my way through the book and YouTube trying to learn everything about this machine.  I will say, once you have it mostly dialed in, the end product is fantastic.  Having live in Italy for a number of years, I knew what I was missing.....  And even though I love my Moka Pot, it just wasn't the same.  Now I'm have great quality espresso.  Remember, DON'T skimp on the espresso beans!!!!
