Your products always work great! Great customer service and a quality product that we have used for years.
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.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
Very easy to install and directions were straight-forward.
All looks very nice. [I chose E.I. because of] previous experience.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Great product at a great price …. (and) reliability.
[Customer service] is great!
Good engineering support.
People [at EI] were great to work with.
We have other EI products currently and have always been satisfied.
