I have a vent directly over my bed. Tried this product to cover it up. Even with the vent switched over to the closed position, if the heat or air was blowing, the magnet in this product is not strong enough to stay stuck to the vent. I even tried to put glue dots around the edge to help it stay put. This worked to keep it in place for about a week. I have standard vent covers in my home.
