Confused By Negative Reviews – GAF Wi-Fi Vent Review

First off I am NOT affiliated with GAF or their app developer. That being said, I’m confused as to why there are so many negative reviews on this product and the app. I installed the gable vent fan using rubber insulator washers placed between the four “L” brackets and wall studs. It is located directly above my home office and I can barely hear it when it’s on (and yes, my hearing is fine!) The app works as advertised so I’m wondering why so many negative reviews? I’m very happy with my purchase and I’m really glad I took a chance and ignored all the negative feedback. This is a good product that is reasonably priced.
