Bests & Worsts Reviews from Amazon

It's exactly what it states. I'm not sure why negative reviews are being left, simply because they didn't read thoroughly? It's a window fan. It gives the exact dimensions. It's not overly loud, but again... still a window fan. It can be used in exhaust form by just turning it the other direction. Very simple and very clearly stated in the description. Half of y'all just don't know how to read, and that's not the fault of the seller or the product. Do better, and stop leaving negative reviews because YOU screwed up.
