Excellent Service, superb product.
Excellent tech help…
Pleasure supporting folks with like values.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
Great… price [&] support
Love the look and having every piece of info in front of me… Better price and look [versus competition].
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
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!
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
