I was replacing a 30+ year old dehumidifier that was running constantly in my basement.  When this unit arrived (2 days after I ordered it), setup took minutes.  I was able to use the existing hose drain attachment and was amazed how much quieter this unit was than the one I replaced.  It ran continuously for almost 24 hours, removing a large amount of moisture.  Now my basement smells better, and the digital humidity readout makes it easy to see where my levels are.  Great unit for the price!
