Review on Flex Lite 31147 Adjustable Temperature by Michael Jenkins

On my car for almost a week. I connected this box to a relay as others have warned and not directly to a fan so the box doesn't have to deal with high electrical current. It works fine, but I was hoping that the lowest setting would leave my electric fan running at a much cooler temperature. I had to set it to the lowest setting to get the fan working where I wanted.
