Customer Testimonials

Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.

Nathan V. from Alaska
Cessna 172C

After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.

Ralph M. from Florida

Nice bright display.

Peter S. from Arizona

Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.

Doug F. from Nevada

Good support when we called with particular questions with the initial setup. We liked the functions and the price.

Tom P. from Wisconsin
Cessna 172S

I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.

Eric B. From Texas
Grumman American AA-5B Tiger

Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.

I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
