All looks very nice. [I chose E.I. because of] previous experience.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!
Your (customer) service is excellent!
Excellent installation instructions [&] recommend[ed] by others.
This is the second product purchased and I am completely satisfied.
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
Nice bright display.
We chose your product because of the great support and reputation your company sustains.
EI tech support is the best.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
