Great customer service!
Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.

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!
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.

[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.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Good to go! Excellent instructions and easy install. Outstanding instrument!
Great service. [I replaced/upgraded] unit in aircraft.

Great product. So easy to read compared to the originals.
Nice unit. EI is the best!
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
