Excellent Service. Superb Product.
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Nice product and good product support!
Great service. [I replaced/upgraded] unit in aircraft.
Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
[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.
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
EI tech support is the best.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
