Review on Frost King 1 Black by Jeannie Story

This product was exactly what I needed to enhance the efficiency of my air conditioner. Thanks to my knowledge gained in practice, i knew that sealing the gaps around the AC unit would make a huge difference IN keeping the cool air in and hot air out. Frost King 1 Black did its job perfectly! The installation was simple and quick and the results were noticeable right away. However, it would have been nice to have had more material in the package..
