Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Phone service for ordering was quick and easy. Shipping was quick.
While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!
Good engineering support.
We chose your product because of the great support and reputation your company sustains.
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
We have other EI products currently and have always been satisfied.
Works Great!
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
Love the look and having every piece of info in front of me… Better price and look [versus competition].
Very affordable… great installation instructions. [I chose EI because of its] price point, certified primary.
