Easy Install.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
Good equipment at a good price. I have used your products before and have had great success.
Met all my requirements; great support.
Excellent customer service. Without a doubt the best aviation part I have purchased.
Straight up install no issues. Works as advertised!
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
Nice unit. EI is the best!
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Sales reps have been very friendly and helpful.
