Gauge works great! Very happy with purchase.
I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
Awesome product. Fast easy installation.
Haven’t used it yet, but we are excited to & Love the way it looks!!
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.
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!
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Very impressed with the clarity and readability of the CGR-30P gauge.
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.
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
