Sharp-looking gauges. [I chose EI because of your] reputation.
Compact, precise, awesome!
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
Very easy to install and directions were straight-forward.
The CGR-30P is a fantastic product and EI has excellent customer service. EI is the leader in engine monitors with a strong track record.
Haven’t used it yet, but we are excited to & Love the way it looks!!
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
Met all my requirements; great support.
