EI has the best customer service of any company that I’ve ever dealt with.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
Great… price [&] support
Great customer service!
I installed a VA-1A Volts/Amps Insturment [sic] in my 1970 V35B to replace the original analog amp meter. What a great dual purpose digital gauge! Installation was simple and the product is very well made. It goes well next to my SuperClock I installed a couple of years ago. EI makes great products and this one will satisfy the most discriminating owner.
Simple and Easy.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
Staff appears to be very helpful when assistance is needed in verifying information. Heard good things about it [EI] from personal known aircraft owners.
Straight up install no issues. Works as advertised!
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
