Great variable speed fan controller

My Flex-a-lite 30332 fan controller i had controlling my 2 12inch Flex-a-lite fans was garbage putting me on a flatbed even bad design connections are always melting and shorting out, cheap plastic housing a circuit board that the connections plug right onto GARBAGE!!!.................So i did a little research and came up with Flex-a-Lite 33054 being the upgrade, ive had it a couple weeks now what a great product i installed it in a couple hours the probe was my least favorite part pushing it through the rad fins yuk!. The main wires that fried on old one now come out of the unit u connect to instead of plug connecting to board. GREAT PRODUCT!!!
