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.
Safety and simplicity!

Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
Phone service for ordering was quick and easy. Shipping was quick.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.

Original clock failed after MANY years of use. Got the same one as a replacement because original one worked so well.
After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.
Electronics International supports their products. Rare repairs are done quickly.
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!
