I've had this unit for a few weeks now and it does a really good job cooling down my apartment. Some reviews claim this unit is really loud and yes, it is a bit loud but I don't think it is any louder than any standard window A/C unit that I've had in the past. The only reason I didn't give the A/C 5 stars is because I thought it was a bit difficult to put together the exhaust hose and window kit. It definitely took longer to install than a traditional window A/C unit. Since that was a bit time consuming, I don't think it would be so 'quick and easy' to move this A/C to another room or window.
