Kleer Vu is a product that is not only excellent for the racquetball industry, but other sports as well where goggles are used. It totally eliminates fogging and steaming on glass or plastic. If put on a mirror that is submitted to extreme heat, the mirror will remain fog free.
Opinion: Kleer Vu does work! It works even better with repeated use and the duration between applications will last longer. It is easy to use due to its convenient containers. I give it a very good recommendation.
