Low quality product. The connection pieces for the hose going from the unit to the window are flimsy and barely screw into place. You can barely move anything without it all falling apart. The actual piece that goes into your window is made for vertical sliding windows not horizontal. I don't think I've ever seen a home with vertical sliding windows it's very inconvenient and It doesn't fit my window properly so I was forced to jam a piece of wood into the window slot to fill the space. Unit is entirely too noisy in AC mode and I'm not usually bothered by noise.
