Very impressed with the clarity and readability of the CGR-30P gauge.

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 experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
People [at EI] were great to work with.
E.I. Always Exceeds Expectations!
Nice unit. EI is the best!
Great customer service!
EI tech support is the best.
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
