Good product, iffy representation
Your review: The fan works well, makes very little noise even right next to it. It definitely helps our dryer exhaust problem. My complaint isn't with the fan's function, but rather with the fact that the image shows the unit assembled and wired to the pressure switch, but it isn't shipped that way, and the wiring isn't evne supplied to make teh connection. The instructions for making the electrical connections are among the worst I've ever seen, and I was a controls electrician for several years.
If the electrical side had been even halfway done, I'd give this unit 5 stars, but as is, I can only justify 3.
