Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
Great Service.
Very impressed with the clarity and readability of the CGR-30P gauge.
EI tech support is the best.
The equipment is fantastic, very intuitive, and easy to use.
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 love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Customer Service is far superior… with an excellent record of resolving … technical issues.
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.
