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 have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
People [at EI] were great to work with.
