I bought this unit because of the rave reviews it got pertaining to cooling, noise level, and portability. From consumer reports to numerous websites they said how this was the best portable unit to date and is the only one comparable to a window unit. I had several guest visiting for the weekend and it was very embarrassing when I had to dig out my old window unit and Jerry-rig it in the window to cool my living-room. The unit just turned two months old when they were visiting. 
If you live in a garden unit it may work much better but anywhere else I do not see it helping.
