that's an interesting design. never seen that anywhere. do they hold the patent but fail to scale beyond italy? I find usual espresso machines to be too complicated and technical - also too expensive.
how does the taste compare to a "normal" espresso machine?
I'm currently using ESE pads with a La Piccola machine but want to move on because of all the trash the packaging of pads makes. The taste is quite good though, even compared to a "normal" espresso machine.
edit: and how hard is it to find the correct temperature? I've often had the problem of my Bialetti getting to hot on the stove
Probably yes. It's just a "new" technology, so I don't know what are their plans for the future.
