I’ve had good experiences with EI products in the past, and customer service very quick and helpful.
The layout and quality is impressive.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.

I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
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.
Installation was straightforward; great quality all around.
