Customer Testimonials

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

Nice unit. EI is the best!

Mark H. from Arizona

Gauge works great! Very happy with purchase.

Aryan M. from California
American Champion 8KCAB

Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.

After a full IFR install on my Cessna 175, my two favorite instruments without question is the CGR-30 Combo set. Simple and customizable, the data is invaluable!

C Scott Van W. From Idaho

Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.

Larry K. From Kansas
Piper PA-28-181

I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…

Anthony H. from Oregon
Piper PA-18 Super Cub

Easy installation.

Excellent tech help…

Ron M. from Canada
Cessna 182Q

[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.

Brett U. from Idaho
Piper PA-28 S-180 Cherokee

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

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.
