Excellent customer service. Without a doubt the best aviation part I have purchased.
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!
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.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
Responsive customer service, kudos to [customer service].
Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
Beautiful graphic display, easy to use, perfect automatic dimming!
Works great!
Sharp-looking gauges. [I chose EI because of your] reputation.
Very impressed with the clarity and readability of the CGR-30P gauge.
