Product review (5 stars): Very pleased so far
I installed this booster about two months ago. It works well so far. My dryer vent goes straight up through the roof about 20 feet, so I needed something that would assist the dryers' blower for that distance since I've had to replace my dryer's' heating element twice. I installed this in my attic upside down because of the air flow direction. I chose this product because of its design to reduce the chance of lint clog and because it is activated by pressure instead of current. Current would have required wiring with the dryers plug which is on a whole other floor of the house. Pressure activates the booster once the dryer starts pushing air through the lint vent. It turns on or off simply by pressure or no pressure. Very pleased so far. This unit hasn't experienced the summer heat of the attic, so I am hoping it can handle it. Other in line blowers, most of which are current activated, have heat limits.
