Customer Testimonials

EI tech support is the best.

W. Bowman from Texas
R172E, T41B

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

Benjamin T. from South Carolina
Piper PA-28-181 Archer II

EI has the best customer service of any company that I’ve ever dealt with.

Greg J. from Georgia
Beechcraft C23 Sundowner

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

Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.

Logan from Montana
Cessna 172B

While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!

Jeffrey S. From Missouri
Cessna 170N

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 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

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.

Nicholas A. From Ohio
Piper PA-32R-300

Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.

Kenneth C. from Florida
Piper PA-32-260 Cherokee Six E

The layout and quality is impressive.
