Customer Testimonials

The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.

Thomas C. from Maine
Maule M-5-235C Luna Rocket

I installed a VA-1A Volts/Amps Insturment [sic] in my 1970 V35B to replace the original analog amp meter. What a great dual purpose digital gauge! Installation was simple and the product is very well made. It goes well next to my SuperClock I installed a couple of years ago. EI makes great products and this one will satisfy the most discriminating owner.

Brewer P. from Mississippi
Beechcraft Bonanza V35B

Works great!

Ronald C. from Colorado
Stinson 108-3

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

We’ve worked with EI for years and love the product and support always received. Quality & dependability.

Easy installation.

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.
