Query: Performs an excellent job!

People were not kidding when they said that the clean-up of this machine is cumbersome, however, it was worth the effort. I used this machine to paint a 20'x50' room at my kid's dance studio and I managed to do it with one coat and with less paint and in half the time than it took to paint the other rooms with a standard roller. The handle does get a bit heavy after a while so be prepared for that.
