Product review (5 stars): Dryer time cut down from 2hrs to 30minutes!
Dryer time has been cut down to a fourth! Our dryer vent run to the outside of the house is 60ft, plus has 4 90deg bends, so no wonder our dryer wasn't working. We used to run 2hour cycles, now down to 30minutes! The current switch works great (I had it installed by a professional electrician, so yes, the whole thing landed up costing up a lot more than the cost of the fan)
