Never buy any surge protector that is not UL or CUL listed. This unit has neither. Buyers beware!
Here’s a link to explain what ETL is.

Thanks for the link pepper114. I know what ETL is and I stand by my comment. Here is an example of a product that has passed the ETL certification but is not UL listed. It is a defective and dangerous product which makes me wonder how it ever got the ETL certification in the first place.
