I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.

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!

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!
Simple and Easy.

Great product. [I chose EI because] you have no competition.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
