[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
Love the instrument, easy to install, all good
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
Your products always work great! Great customer service and a quality product that we have used for years.
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.
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
Good to go! Excellent instructions and easy install. Outstanding instrument!
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!
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
Great tech support. Someone always answers and gives accurate concise information.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
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!
