This works great! We acutally bought 2 we were so happy with the first one!  So much easier then window units.  Really cools off the room.  We have not tried the heater part yet but that will come in handy in the winter for sure!  I looked at so many and this had the best reviews all around on many differnt sites all had the same positive reviews.  Don't be stressed about this purchase you will be really happy with it :)
