Nice product and good product support!

Outstanding Customer Service!!

Rocky C. From Texas
Mooney M20F

Great service for Electronics International.  Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.

Ralph J. from North Carolina

I have seen your products in other aircraft and have seen their reliability.

Juan P. from British Columbia, Canada

Sales reps have been very friendly and helpful.

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

EI tech support is the best.

W. Bowman from Texas
R172E, T41B

The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.

Casey R. from Oklahoma
Cessna 172M

EI shines in providing excellent customer support and its products are reliable, affordable and of high quality.

Fernando D. from Iowa

Awesome Tech Support. Like the functions it supports and the fit and look in the panel.

Brian M. from California

Compact, precise, awesome!

Harvey C. from Maine

Easy to install, and the CGR was set up to my aircraft’s exact specifications.
