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!

Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
We have other EI products currently and have always been satisfied.
Responsive customer service, kudos to [customer service].

We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
