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!
EI’s team is great; you guys are the best.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Great tech support. Someone always answers and gives accurate concise information.
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!
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
I have worked with your products before and I like them.
Outstanding Customer Service!!
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
