Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
Excellent tech help…
Responsive customer service, kudos to [customer service].
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.
. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.
Nice product and good product support!
Gauge works great! Very happy with purchase.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
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.
