Responsive customer service, kudos to [customer service].
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
Excellent installation instructions [&] recommend[ed] by others.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
We chose your product because of the great support and reputation your company sustains.
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.
Haven’t used it yet, but we are excited to & Love the way it looks!!
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
Why did you choose our products over the competition? Complete kit and ease of installation.
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
Easy installation.
