Customer Testimonials

Customer support is great (and the) user interface is superior to other products.

Earl L. from Idaho
Cessna 170B

Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.

David C. from the United Kingdom
Scottish Aviation Bulldog

Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.

Larry K. From Kansas
Piper PA-28-181

Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…

Terry R. from Washington
Van’s RV-6

Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.

Easy to install and everything you need inside package. Good price, nice instrument and simple to use.

Pantelis K. from Greece
Piper Seneca I

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

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

The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.

Thomas C. from Maine
Maule M-5-235C Luna Rocket

Very impressed with the clarity and readability of the CGR-30P gauge.

Richard K. from New York
Piper PA-28-181 Archer III

Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.

Justin R. from Texas
Cessna T207A Turbo Skywagon

We chose your product because of the great support and reputation your company sustains.
