Put it up last night and cool up my Mom's room so quick the only minor down side is noisy, its a little noisy more mine. I have the  FFRE0633U1 model 2years ago and its 6000 TBU same things unfortunately I could find it  anywhere...However its okay its not too bad. My Mom said the noise is fine to her. It's a great buy! [This review was collected as part of a promotion.]
