Customer Testimonials

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.

Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.

Eric H. from Mississippi
Beechcraft C23 Sundowner

Why did you choose our products over the competition? Complete kit and ease of installation.

Mitch G. from Canada
DeHavilland DHC-2 beaver

Great Product, that provides a lot of very helpful engine data in an easy to use and see display!  We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive.  The CGR-30 had quite a few positive reviews online from other users.

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.
