Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
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.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
Met all my requirements; great support.
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…
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
Sales reps have been very friendly and helpful.
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.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
The tach looks and operates amazing. Extremely accurate.
Safety and simplicity!
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
