Sales reps have been very friendly and helpful.
Best sales team.
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.
New Tachometer is amazing . . . Engine Performance analysis at a whole new level!
All looks very nice. [I chose E.I. because of] previous experience.
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
Great system and great benefit having everything in one place. Love it.
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
Love my new engine monitoring system.
Great product, frees up space
