Works great.
Arrived right on schedule. Installed it on my generator and now I have electricity... It came set at 110 volts, I easily adjusted it up to 120 and now I can run my outdoor fans... It is too soon to say how long it will last, but well worth the price...

Finally a company product that works
Been trying to get an AVR that works. Others ordered from other companies failed and would not work. Purchased this one and it works great. All I had to do was tweek the voltage screw to increase it from 117VAC to 121.9VAC. I'm ordering another just for a back up. Its worth the cost to have this in stock ready to go during the winter in the event of some type failure. Its an electronic device so you never know.

The new AVR was a good replacement
My generator was not generating the proper voltage. I had power but not full power from the generator. The new AVR fit perfectly and fixed my generator issue!

Universal
Universal AVR, as long as yours has a connector already and is pointed the same there aren’t any issues. Potentiometer is nicer for adjusting the voltage when needed.
