[I chose the CGR-30P because of its] ease of use.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Pleasure supporting folks with like values.
I have several EI units in my aircraft and have been very pleased with their reliability over the years. The other great part, besides the unit themselves, is the support from you all. Thank you for your support over the years… I chose IE for your reputation for quality and pricing. I have been very pleased with my units. My graphic engine analyzer, fuel flow meter, volt/amp meter, RPM and now Manifold gauge.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
Works great!

You folks do a great job. Keep up the good work.
Good engineering support.
