Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.

Nice unit. EI is the best!
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
I really enjoy your products [because they are] simple and easy to use and affordable.

Great service for Electronics International. Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.
. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
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.

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
