I purchased this air conditioner 2 days ago and as promised, it came today. It was fairly easy to install. The tubing that connects to the window is only for larger windows, but I was able to cut it down. As far as cooling, it's ok. For me, dry did absolutely nothing for 6 hours. I had it in my small bedroom on dry to remove humidity and it did absolutely nothing. Cool is better and the only feature I'm using right now. So far, it's ok. I haven't had to change any filter and I'm not sure what that clear short tube is for. It doesn't explain what in the instructions. Oh, and it's very loud.
