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.
The tach looks and operates amazing. Extremely accurate.
Fantastic customer support!
[I chose EI because of its] Reputation and value.
Works great!
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.
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
Keep it up. I’ll keep coming back.
Excellent Service, superb product.
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.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
