This engine speed controller works great! It's easy to install and appears to be durable. I've had one installed in my boat for several months. It is powered by a 4 inch bilge fan which I use to circulate the air. This fan runs 24/7 and I've had no problems. With speed control I can slow down the fan to make it quieter. I just bought another one to control the interior heater fan.
