We bought this unit about a year ago, used it pretty much only on weekends, nice while it worked, but it didn't last long!  The Milk Frother Unit clogs up very very easily with its very small aperture, Impossible (thus far) to find a replacement part for the Frother Head Unit ... one would think that as easily as these clog and difficult/impossible to really clean that they would at least sell replacement parts for them ... but No!   My advice ... spend a little more and buy a better-quality unit than this "cheap" option.  You'll be buying a nother unit when this one fails in a year or so anyway.  Cheap quality ... cheap price!
