I have one of those from a different manufacturer, or should I say different label on it, typically my luck with electrical things from Vivosun has not been good. The one I have has been running nonstop for 2 years now. My only complaint is the 8" ducting doesn't fit well on its own so I had to use duct tape to seal it up. I am deaf so the noise doesnt bother me, no complaints from my wife but I am deaf so I may be missing them
