Customer Testimonials

Easy install, good product. [I chose EI because of my] experience with [the] product.

Dave S. from Missouri
Beechcraft Bonanza Model 35

Your products always work great! Great customer service and a quality product that we have used for years.

Brenton C. from Tennessee
Cessna 172M

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

Daniel N. From California
Cessna 175 Skylark

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

Big improvement over old cluster (gauges).  Good customer service.

William P. from Louisiana
Cessna U206

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

I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You

Gregory V. from New Hampshire
Cessna A185F Skywagon and AgCarryall

Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.

Jon V. B. from Illinois
Cessna 172F

While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!

Jeffrey S. From Missouri
Cessna 170N

Installation went great. The Fuel Flow is dead on.

Tyler A. from Tennessee
Piper PA-32RT-300T

The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.

Casey R. from Oklahoma
Cessna 172M

Works great, super install.
