Looks great. Works great.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
People [at EI] were great to work with.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
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 older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
Easy installation.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
We liked the price and the reputation of your company.
