Awesome product. Fast easy installation.
[I chose the CGR-30P because of its] ease of use.
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.
Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…
Excellent installation instructions [&] recommend[ed] by others.
Sharp-looking gauges. [I chose EI because of your] reputation.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
Customer Service is far superior… with an excellent record of resolving … technical issues.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
Keep it up. I’ll keep coming back.
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
