This was an easy buy, as we already have a larger Frigidaire unit that has performed flawlessly for years.

The new 5K unit is installed in a bedroom, around 120 square feet.  Cooling is rapid, it's quiet, it maintains temperature nicely, and the remote control is good.

We use a pair of rubber panels (cut out from one of those 2'x2' black shop pads) behind the accordion pieces to completely seal it so mosquitoes can't get in.
