. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.
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.
