Product review (5 stars): It really works and is easy to install
This is an excellent product. I've had it for many years. It does an excellent job of keeping the cold air from coming into my dryer. I noticed that every time I opened my dryer door cold air was coming in. It lengthened the drying time and they seemed to feel wet. I checked the vent outside and realized the top had come off and the float was missing. This plays a very important role in stopping cold air from coming inside. I ordered a new one and replaced all the parts in minutes. This time I will paint it with house paint to keep it from cracking.
