He's right but he's also kinda wrong. It has a boiler and a Thermoblock (not technically a boiler) with two separate pumps so you can steam and brew at the same time if you want. Source: I own the machine and do it all the time!

Ben, do you like this machine? I have a Mignon grinder and a Breville Bambino and I was going to stick with that basic setup for a while. Problem is I started watching too many videos and hanging out in too many forums and before I knew it, I had myself ready to spend a large amount of money. In the interest of being somewhat reasonable, I'm going back to the drawing board and trying to find something more reasonably priced. We drink straight espresso and milk drinks equally in my house. Thanks!

18 or 19G should be good for that machine but maybe grind could have been a little tighter since the pressure gauge was reading a bit low. I don't normally check but last time I looked it started at around 9bars (which is the pressure setting I set it to, *you can adjust it yourself with a flat head screwdriver on this machine!) and it gradually dropped to 8.2 ish by the time the shot was flowing faster towards the end of the shot.
