I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.

Thomas W. from Virginia
Piper PA-30 Twin Comanche

People [at EI] were great to work with.

Andrew & Carri Ann M. from Alaska
Piper PA-18-150 Super Cub

A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.

Adam S. from New Zealand
Cessna 172N Skyhawk

Simple and Easy.

Aaron H. from Washington
Cessna 140

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.

David M. From South Carolina
Cessna 182J Skylane

Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.

Justin R. from Texas
Cessna T207A Turbo Skywagon

Easy installation, lightweight solution. It looks good and is easy to use.  [I chose E.I. because] I needed to replace my old Hobbs meter.  This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.

Thomas M. from Arizona
Rutan Model 61 Long-EZ

Sharp-looking gauges. [I chose EI because of your] reputation.

Garrett R. from Alaska
Beechcraft King Air Model B100

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
2002 Diamond DA40-180

Haven’t used it yet, but we are excited to & Love the way it looks!!

Larry A . From Idaho
Piper PA-28R-200 Arrow

This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!

Karl P. from Maine
Stinson 108-1

I have seen your products in other aircraft and have seen their reliability.
