Customer Testimonials

Outstanding customer attitudes; prior experience said you’re the right company to do business with.

Hillel G. from Maryland
PA28-180G

After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.

Ralph M. from Florida

Best sales team.

Russell S. from Iowa

Love the look and having every piece of info in front of me… Better price and look [versus competition].

Gregg J. from Indiana
Piper PA-32R-301T

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!

Charles M. from South Dakota
Cessna 150F

Excellent installation instructions [&] recommend[ed] by others.

Ben C. from Alaska

Have had EI instruments in my past plane and current plane and they always performed flawlessly.

Gary M. from California

Original clock failed after MANY years of use. Got the same one as a replacement because original one worked so well.
