Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.

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!

Phone service for ordering was quick and easy. Shipping was quick.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Good equipment at a good price. I have used your products before and have had great success.

I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!

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.

Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
