Been using this for about a week now, and can say it works like I intended. Don't expect it to work like a window ac as its not its purpose due to this item power draw typically under 200W, but is exactly what I was looking for. Takes enough of the heat away to not be too uncomfortable while working in areas that are poorly insulated/ventilated like attic or unfinished rooms. Seller sent this item well protected and everything works just great!
