This makes an excellent frothy cappuccino, plus it makes an awsome crema-espresso when brewed without the milk!
Negative Product Points
The plastic pressure valve will eventually need replacement when it loosens and fails to keep a good seal. Also, the washer on the pressure plate may fail to seal properly, causing leaks that can make a mess of the stove.
Detailed Commentary
This mokapot will make an excellent frothy cappuccino in one simple process, rather than brewing the coffee/espresso, then steaming/nuking & frothing the milk. This mokapot will also produce crema-espresso ala my 2-cup Brikka, only in the larger size comparable to a 4-cup Brikka. This is the part I like, since the Brikka makes the best black coffee, even better than my Moka Express. So when I sampled the espresso from the Mukka, I was flabbergasted! It was just as creamy and therefore tasty as the Brikka, only more of it.
Purists say that the stovetop moka pots can't reach 9-bar pressures, and thus cannot produce true espresso, but for my money (and I've saved a lot over an expensive high-end true espresso machine), the "espresso" produced by the Mukka and Brikka by far give the best bang for the buck!
Buying Experience
Good. I bought my two Mukkas from Ebay, one used (with box, measuring cup, instructions and dvd) and one cherry-on-the-inside, scratched-up demo model (no box, nor anything else).
