Easy installation.
Great service. [I replaced/upgraded] unit in aircraft.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Great customer service!
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Outstanding Customer Service!!
I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.
Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
Works Great!
Incredible customer service.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
