After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.

Customer Testimonials
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
You folks do a great job. Keep up the good work.

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.
Your products always work great! Great customer service and a quality product that we have used for years.

Pleasure supporting folks with like values.
Great product at a great price …. (and) reliability.
Great customer service!
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!
