Excellent customer service. Without a doubt the best aviation part I have purchased.
Pleasure supporting folks with like values.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
Straight up install no issues. Works as advertised!
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
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!
Love the look and having every piece of info in front of me… Better price and look [versus competition].
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
