Good equipment at a good price. I have used your products before and have had great success.
The tach looks and operates amazing. Extremely accurate.
I have worked with your products before and I like them.
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.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
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.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Great service. [I replaced/upgraded] unit in aircraft.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
We chose your product because of the great support and reputation your company sustains.
Very impressed with the clarity and readability of the CGR-30P gauge.
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!
