Easy install.
Sharp-looking gauges. [I chose EI because of your] reputation.
The tach looks and operates amazing. Extremely accurate.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
MVP-50 is a really great product
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
Great customer support. My A&P installed a CGR in a Comanche and liked it.
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
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.
Nice product and good product support!
Love the look and having every piece of info in front of me… Better price and look [versus competition].
Good engineering support.
