Review on UV Sterilization Disinfection - Three-Step Germicidal Solution by Sandra Saksena

Works great. only one problem The light flashes once when you press one of the timer buttons. Be careful not to look into the light. This can damage your eyes. I am allergic to mold and have disinfected the room. So far I think it has worked. I used it for over an hour and gave the room 24 hours for the ozone to clear. Just remember that the longer you use it, the more ozone will be produced, so plan for it.
