Review (1/5): Does not emit UV light.
This product simply does not do what it advertises. It will not sterilize. No UV light is emitted.
As an optometrist, I have instruments to evaluate what type of light is emitted from the machine. There is little or no UV light coming from the bulb. This feels quite a lot like a scam. As UV light is not visible to the human eye, this can be hard for the average person to verify, so I send my warning.
