I love this thing. I don't know how I ever survived before I got it. So, my boyfriend had to set it up for me. Simple enough. Great value for the price. Cold air, dehumidifier works like a dream, makes my bedroom so comfy. I've got it sitting on a stool, with mop bucket to catch the water it pulls from the air, and it is vented so you'll have to have it near a window. Check your bucket often, the first two days, this thing pulled 3 mop buckets full.

Louder than we anticipated, but works well. Showing room temp when off is a nice touch. So is the dual temperature conversion, so we are not stuck with the US version.

Very pleased with my purchase and delivery I just should have had more knowledge/research about portable air conditioners. Walmart is one of my favorite places to shop.
