works like a charm.easy to install.just adjust the knob to the temperature you want the fan to turn on.only downside is if you do not wire it to the key switch it constantly turns on and off when the vehicle is switched off

Worked great, description matches what the unit does. Easy to install and replaced a faulty FlexLite unit. The only thing missing is the ability to have a manual switch to turn the unit on. I got around this by installing a second relay that bypasses this automatic unit.

This item is 100% better than the old one. The price I paid was not the cheapest nore the most expensive. The control is just what I needed.
