I was less than impressed with this product. For $80 I expected to get more than a little fan in a PVC housing. THe fuse wasn't even attached. The instructions say not to glue the vent pipe to the fan housing, but no alternative method of providing a secure airtight connection is provided. It was nice of them to provide the voltage set points, but I expected, and this may be due to my lack of diligence researching the product, some sort of control to be included with the unit. The cheapest voltage controlled switch I have been able to locate is over $100 and is backordered 4-6 weeks.
