Customer support is great (and the) user interface is superior to other products.
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!
We chose your product because of the great support and reputation your company sustains.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
Great… price [&] support
Great customer service!
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
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.
All looks very nice. [I chose E.I. because of] previous experience.
