Rodney E. from Georgia

This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!

I like how the kits ship with everything needed for install and the wire labeling was very helpful.
