“Works well, but....”
We bought two of these about a week apart in early August. One went in my garage and the other in the mother-in-law's house.
If you're looking for something cheap that blows cold air and is reasonably quiet and efficient, then you'll be happy. For anything beyond that though, exercise caution and understand that you're getting (maybe) what you pay for.
First and foremost, these are made in China; they are cheap and they show it. They were not well boxed and both (from two different Sears locations) had dents and distortion in the outer cases. The grilles don't fit well and don't want to stay on, and the access door for the filter doesn't like to stay shut. As someone else mentioned the side curtains are a bear to install due to sloppy machining and lack of clearance to get to the screws. And, the holes in the bottom of the frame for the external supports that go beneath it on the windowsill are drilled such that they're pretty much useless. They did not line up with anything useful on either installation. In once case I drilled new holes; in the other a drill was not available so I rigged something with scrap wood.
Finally, there was something in the instructions about making sure that the drain hose was attached to the outlet hole. that evidently was for an earlier design. These units simply have a notch at the back that lets condensation drain out of the bottom of the unit. So, I wound up pulling the unit out of the case for the fun of it.
Bottom line: So long as you understand that they look like **** and may require some creativity during the installation process, you'll be fine. But, if you're looking for something that installs easily and goes together properly as well, spend a little more and get a name brand built elsewhere.
