Simple and Easy.
We chose your product because of the great support and reputation your company sustains.
Phone service for ordering was quick and easy. Shipping was quick.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
Your customer support is far superior . . . . I appreciate all your help.
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.
I have several EI units in my aircraft and have been very pleased with their reliability over the years. The other great part, besides the unit themselves, is the support from you all. Thank you for your support over the years… I chose IE for your reputation for quality and pricing. I have been very pleased with my units. My graphic engine analyzer, fuel flow meter, volt/amp meter, RPM and now Manifold gauge.
Great service. [I replaced/upgraded] unit in aircraft.
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
Beautiful graphic display, easy to use, perfect automatic dimming!
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!
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
