E.I. Always Exceeds Expectations!

Michael S. from California
Beechcraft Bonanza Model 33 Debonair

Great Product, that provides a lot of very helpful engine data in an easy to use and see display!  We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive.  The CGR-30 had quite a few positive reviews online from other users.

Ryan O. from North Dakota
Cessna 182D

We liked the price and the reputation of your company.

Roy C. From Kentucky
Piper PA-28-235 Cherokee Pathfinder

Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.

Nathan V. from Alaska
Cessna 172C

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

Ben C. from Alaska
Piper PA-22-160

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

Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.

David K. from New Mexico
Cessna T20N Turbo Centurion II

I have worked with your products before and I like them.

David K. from New Mexico
Cessna T20N Turbo Centurion II

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

Excellent Service. Superb Product.
