[I chose the CGR-30P because of its] ease of use.
The layout and quality is impressive.
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.
Great service and support for great products!
Great service. [I replaced/upgraded] unit in aircraft.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
Very easy to install and directions were straight-forward.
Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
Easy install, good product. [I chose EI because of my] experience with [the] product.
Your customer support is far superior . . . . I appreciate all your help.
