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

Awesome product. Fast easy installation.

Rodney E. from Georgia
Cessna 172M Skyhawk

The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.

Daniel N. From California
Cessna 175 Skylark

E.I. Always Exceeds Expectations!

Michael S. from California
Beechcraft Bonanza Model 33 Debonair

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

Excellent Service, superb product.

Steven N. from Colorado
Cessna 182E Skylane

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

Brian M. from California
Mooney M20F Executive 21

EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.

Phillip B. From Oklahoma
Cessna 210N Centurion / Turbo Centurion

The display is large and clear. The functions are simple and easy to use. Great purchase decision.

Stephen J. From Texas
Beechcraft Bonanza K35

Works Great! Love it!

Rick C. From Florida

Excellent Service. Superb Product.

Steven N. from Colorado
Cessna 182E Skylane

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!
