Customer Testimonials

I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!

Christopher W. from Texas
Cessna 172

Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.

Eric H. from Mississippi
Beechcraft C23 Sundowner

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

Works great!

Ronald G. From Washington
Cessna 195A

Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.

Todd M. from Ohio
Cessna 195

A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.

Adam S. from New Zealand
Cessna 172N Skyhawk

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

Brian M. from California
Mooney M20F Executive 21

Easy Install.

Leslie S. from Connecticut
Piper Arrow PA-28R-200

I have several EI units in my aircraft and have been very pleased with their reliability over the years. The other great part, besides the unit themselves, is the support from you all. Thank you for your support over the years… I chose IE for your reputation for quality and pricing. I have been very pleased with my units. My graphic engine analyzer, fuel flow meter, volt/amp meter, RPM and now Manifold gauge.

Boyd G. from Arizona
Cessna 182J Skylane

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
Cessna 150L

We’ve worked with EI for years and love the product and support always received. Quality & dependability.

Tammy B. from North Carolina
Air Tractor AT-802

[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
