There have been a few posts on the Bialetta...I've linked one below. BTW, I've had mine for 2+ years and use it constantly.

Here is a link that might be useful: Bialetta Mukka

mbobden,

I was one who used mine mostly without milk. I did replace it with a plain Bialetti Moka pot for daily use, since I normally do just black coffee.

One difference I noticed between the Mukka and the Moka :) is that the basket for the grounds in the Mukka is smaller than the original Moka pot. But I was still able to make strong enough coffee for me.
