I love the idea. And, when I have put everything together properly, I like the result. The problem is that, for reasons I cannot quite figure, sometimes I don't put everything together correctly. And then I get leakage on my gas burners. I have tried tightening better, using a lower flame, and making extra sure that edges of the upper and lower parts are nice and clean. And still, somehow, I get it wrong about 1/3 of the time. Maybe I am a dope or just plain mechanically impaired. But even if that is the case, I don't have trouble with any other coffee making devices. So I give up on this, and will return to my Bialetti Moka Express, and use a frother and my microwave to make nice, hot foam. Not only will this be easier, it will also give me more flexibility in tailoring the taste just right.
