Review on 💨 Black Flex-a-lite 31163 Variable Speed Control Module with Threaded Temperature Sensor - Enhanced SEO by Sfl Richardson

I have both installed on my truck. One works great and the other has died since installation. It's a little frustrating. Due to the coronavirus restricting my budget I wasn't able to install until recently and my refund period had already passed so I'm sticking with it. The instructions are very clear, a working controller does the job perfectly. But when I get a faulty device, I have a 50% success rate.
