The DeLonghi Pinguino Air Conditioner is such a smart choice for people in need of a little extra cooling in their homes! My better half purchased our a couple of years ago when he realized his office was getting much warmer in the Summer than the rest of the house. Being hot natured, he thought a portable air conditioner would be a smart choice. We've loved it! It's on wheels, so you can move it from room to room quite easily (even my 10-year-old has been known to move it.) It's outside vents attach to an adjucstable plate that fits right in any size window in seconds. Just select what temp you want it and... done! Super easy.Right now we're currently using it instead of our central unit while the temps aren't too very high.
