Low quality cheap foreign made product. Economy button is useless, on other brands when you use that button let's say you set the temp on 72 degrees the entire A/C unit would shut off and not come on again until it got to that temp again not this one the fan still keeps running which is a real pain in the rear I don't like that that at all! It's also very hard to adjust and try and get the air to blow in certain direction. I don't like the fact it has vents on top of the unit as it rains that increases the chances of mold to develop inside the unit. Vents on the side are good enough.
