[Customer service] is 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.
I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
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!
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
[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.
EI tech support is the best.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Nice product and good product support!
