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!

Charles M. from South Dakota
Cessna 150F

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.

Mike D. From B.C. Canada
Cessna 210B

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

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

Beautiful graphic display, easy to use, perfect automatic dimming!

Ryan G. from Washington

Great tech support. Someone always answers and gives accurate concise information.

Thomas M. From Georgia

I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.

Charles M. from South Dakota
Cessna 150F

Have had EI instruments in my past plane and current plane and they always performed flawlessly.

Gary M. from California
Cessna 182Q Skylane

Love the look and having every piece of info in front of me… Better price and look [versus competition].

Gregg J. from Indiana
Piper PA-32R-301T

Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.

William F. from Maryland

Works Great! Love it!

[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
