Product review (5 stars): Prevents Condensation Inside The Dryer
A simple and cheap vent hood that works as intended. I had trouble with condensation inside my dryer during the summer because the exhaust duct that runs to the exterior of my house had a flimsy cover with no flap to prevent air from flowing back in. I bought this and installed it with self-drilling screws and now my dryer's interior is dry all the time. The flap opens when the dryer is running and stays shut when it's not. A must-buy if you have any appliance that runs to the exterior of your house.
