Hey guys I have this vivosun 6" ventilation fan model #306204-6 and the thing plugged in goes 100% and blows shit everywhere. Lol. I picked up a cheap controller from Amazon and it didn't work. So I just got the vivosun since it said it would work as a speed controller just what I need. I don't need a fancy Wi-Fi thing I already have a timer like that. Lol. This thing doesn't work either. It's on or off. Did I get a defective model? It has a three way switch for Var/OFF/Full. It's all on or off. All the way.
