So far so good. The fan is working well. Everything arrived as advertised and in a very timely fashion. Infinigi's fulfillment process was excellent. I was able to follow the install instructions without issue and the fan is operating as expected. It's just been a week or so but I'm happy with the fan at this point. Noise is minimal. I installed it in a freestanding garage with open attic space (standing on the floor of the garage I can see the underside of the fan). I can hear a slight noise if everything else is dead quiet but it is minimal and blends into general white noise. If it stays at that level, I'll be happy. I was able to position the fan and panel so it is operating during the warmest parts of the day - it starts up about 10am and runs until a little after 6pm in May here in So Cal. At this point, I'd recommend the fan. Holding out final judgement until it has a few thousand hours of run time, but as long as it holds up - great product.
