We’ve worked with EI for years and love the product and support always received. Quality & dependability.
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
Very impressed with the clarity and readability of the CGR-30P gauge.
Best sales team.
Great tech support. Someone always answers and gives accurate concise information.
Easy installation.
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.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
Love the instrument, easy to install, all good
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Well documented installation process and Support was helpful.
The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
