I got the portable A/C because I didn't want to install one in the windows.  I wanted to be able to move it from room to room.  This one rolls extremely easy.  It's very quite.  I am really enjoying that it has a remote to control it all.  The dehumidfiyer works great.  It's extremely easy to operate.  You don't have to drain any water because it evaporates.  I have used this unit all over my house depending on what room Im in and it works excellent.  Has 3 fan speed funtions.  I can't say enough good things about this unit.  I highly recommend.
