A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
[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 have other EI products currently and have always been satisfied.
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.
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
Excellent customer service. Without a doubt the best aviation part I have purchased.
Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
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.
Straight up install no issues. Works as advertised!
