We got this unit for a bigger room in our house after picking up the 8000 BTU unit for our bedroom. Keeps the rooms nice and cold and unlike one of our other purchases it didn't come with a funny smell.
I've never owned a rolling type air conditioner in the past. This one sold me. It seems to cool much better than a window unit does. Additionally, one can move the unit so that the air is focused on the area of the room (like the bed) where one needs more coolness. In my case, I was able to position the unit so that it was not blowing air towards my back door. The heat function I have not used much as we have decent gas heat. I would have given this five stars; but, when I did use the heat, it was necessary to repeatedly empty the water accumulation. Why I don't know.
