d this a couple of weeks ago and have used it a few times. I have to say it works great and is extremely quiet. Seems to be a well built device. It was easy to install, which I did by myself. One thing that was a bit awkward was attaching the side pull outs to the the a/c box. It was sort of a pain to get at the screw holes, especially if you don't have a long handle screw driver. I also like the fact that there is an app for this so you can control it from your phone as well as a sturdy, functional remote. Overall I am very pleased with this device.
