Found myself looking at these yesterday & feeling that i needed one in my life.
I already have a caffettiera & coffee machine both of which make ok coffee but i am led to believe that these stove top ones take coffee to the next level.
I use a decent freshly ground coffee so am sure its not that.
So opinions please. Are they worth the £20 - £30 they cost or are they a case of the emperors new clothes?
