I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You

Looks great. Works great.

Stephen W. N. from Texas
Cessna 177 Cardinal

I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.

Brian C. from Florida
C182P

Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.

Robert B. from California

Excellent tech help…

Ron M. from Canada

Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.

Good engineering support.

Richard B. from New Mexico

Excellent customer service. Without a doubt the best aviation part I have purchased.

Alan B. from Florida

I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
