EI has the best customer service of any company that I’ve ever dealt with.
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
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!
Great customer service!
I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!
Responsive customer service, kudos to [customer service].
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.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
Good engineering support.
Incredible customer service.
Good to go! Excellent instructions and easy install. Outstanding instrument!
Big improvement over old cluster (gauges). Good customer service.
