I have one, a KOYO & Dual FAL's... I live in Chicago with high humidity and a lot of Stop 'n Go. I got mine b/c I needed a new one, I found one for $30.00 new, and could actually use it. I have a Greddy Multi-Switcher unit, that I'm using as a fan controller, it reads roughly 155*-165* Average. My old was broken and running open, during the fall, so my car was COLD and that's bad, so it was a neccisary for me. It isn't "needed" for-say, but if you need to replace your current because it isn't working right, I'd say go for it.
