Since I'm moving to a place with central AIR CONDITIONING, offering.
Royal Sovereign ARP-2412.
Keepinged my ~ 400sq. ft 3-room house cool for the last 3 summer seasons. It works on a thermostat and has a timer, which is perfect to establish the A/C to cool down the area down just before you get home on a warm July day, and a sleep timer to avoid awakening in an ice box.
It has functioned well in a basement, where the home window is 5' from the floor, the exhaust tube gets to the home window where a glass adapter keeps it in position. Few devices do this.
Great condition, consists of the unit and remote, not a problem in the time I have actually had it.
