Summary: This air conditioner is very efficient. Even with running it almost 24/7 our energy bill did not increase, it only used about 150 kilowatts in a month. Simple push button controls make it very easy to use. Also, the company that ships these on Amazon was very fast, we received ours within 5 days.
Summary: I bought this last summer to use in a new home I purchased that has no air conditioning. It was crappy then it's crappy now. Tonight I had it going full blast and it said the ambient air temperature is between 76-78. The out door temperature is 81 or so.
Summary: I use this AC to cool my bedroom that's about 225 sq. ft. The manufacturer claims this unit is capable of cooling easily upto 250 sq. ft. I've been using this AC for a week. The air it puts out is definately cool but this AC cannot cool the room more than 2-3 degrees, yes, farenheit.
Summary: It gets the job done, but its pretty big. The two fan speeds put out super noise, so I'm going to have to return it, I'm just trying to cool an avg size room, so this one just won't work for me.
