Gcobup 4-in-1 Portable Air Conditioner

I have a mother-in-law studio apartment in the far northwest corner of my historic old home. It is on the end of a long run of ducting from the HVAC system and receives almost no air conditioning. I was invited to test this unit so I read the reviews of this air cooler and decided to give it a try as it can get very hot in the late afternoons during the summer months and uncomfortable warm in that part of the house. To my surprise, this little unit out performs my expectations. The room is about 300 sq ft and this unit cools the room beautifully. Fill it with water and a bit of ice, and you have instant cool blowing through the room. I'm completely satisfied with the ease of operation and the cooling this unit provides while taking up nearly no space at all. I would recommend to anyone looking for a good room air conditioner that operates efficiently and is very cost effective to purchase.
