We have had this air conditioner for about two and a half years now and it has worked very well during that time. I cannot remember what I paid for it though. We originally had it in our living room, which is very large and open, so it obviously didn't cool the room down completely by itself- although it did help to cool it downon the hottest days. Last summer the air conditioner in my bedroom died and that's when we moved it in there. My room is a decent size, not huge, but it is next to the attic and hot air from there seeps in. The frigidaire air conditioner worked fabulously. It cools down the room within minutes and maintains the temperature you set it too throughout the night. However, it is a little loud if you sleep close to it, like I do- so you have to be a good sleeper if you want it for your bedroom. But overall, it does a great job at what it is made too- cool down a room. If you need a new air conditioner recommend this brand and model.
