Awesome product. Fast easy installation.
Great product. [I chose EI because] you have no competition.
Very easy to install and directions were straight-forward.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
Works Great!
EI tech support is the best.
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
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!
Your customer service is excellent and your products are top quality!
Gauge works great! Very happy with purchase.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
