The R-1-6 is a great instrument. [I chose EI because of] quality.
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
Sales reps have been very friendly and helpful.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
Easy Install.
E.I. Always Exceeds Expectations!
Very easy to install and directions were straight-forward.
EI has the best customer service of any company that I’ve ever dealt with.
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.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
