I like how the kits ship with everything needed for install and the wire labeling was very helpful.

[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.
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
Awesome Product! Great product and fantastic support!
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
Beautiful graphic display, easy to use, perfect automatic dimming!
My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
Excellent customer service. Without a doubt the best aviation part I have purchased.
Looks great. Works great.
EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
