Customer Testimonials

I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.

Brian C. from Florida
C182P

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

Eric H. from Mississippi
Beechcraft C23 Sundowner

Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.

Robert W. from Wyoming
Cessna 182H Skylane

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
