Easy to install, and the CGR was set up to my aircraft’s exact specifications.
. . . 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.
Easy installation.
We chose your product because of the great support and reputation your company sustains.
Big improvement over old cluster (gauges). Good customer service.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
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.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
Compact, precise, awesome!
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Love it!
