Nice bright display.
Works great!
The reviews online were very good. Customer service has been great.
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
EI has the best customer service of any company that I’ve ever dealt with.
Excellent installation instructions [&] recommend[ed] by others.
Compact, precise, awesome!
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.
Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.
Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
