Product review (5 stars): This little gem has been the BEST purchase I could have made
This little gem has been the BEST purchase I could have made!  I installed this whisper quiet fan in my garage to aid with an extremely long dryer vent (2.5 stories straight up).  Before the install I could count on a single load of laundry to take 40-60 minutes to dry, once the fan was installed, I virtually could remove the load from the dryer a the same time the washer was completing its cycle.  My electric bill has gone WAY down as the dryer run time is nothing compared to what it had before.  5-stars is not enough to express my happiness with this product.  I didn't connect this device to my dryers electric system at all, I simply mounted it, placed a timer on the wall, plugged in the fan and set the timer for 25 minutes.  Very easy, hit the dryer start button, hit the timer and they both ended at the same time.  GREAT DEAL!
