Great service for Electronics International.  Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.

Ralph J. from North Carolina
Cessna 150L

I have never had an issue with any EI products… it looks fantastic on the panel.

Thomas A. from Oklahoma
Beechcraft Bonanza E35

Great product, frees up space

Theodore S. from Florida
Cessna 182Q Skylane

The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.

Charles M. from South Dakota
Cessna 150F

People [at EI] were great to work with.

Andrew & Carri Ann M. from Alaska
Piper PA-18-150 Super Cub

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
Mooney M20C Ranger

Very happy with our new tachometer!

George C. from Texas
Cessna 172k

Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.

Logan from Montana
Cessna 172B

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

Responsive customer service, kudos to [customer service].

James A. From Alabama
Cessna 182B Skylane

[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
