We have other EI products currently and have always been satisfied.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
Some of the best customer service in the avionics network that I’ve had the pleasure of dealing with. [I chose EI because of the] features, simplicity, and the user-friendly platform.
Best sales team.
