Works great!
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
[Customer service] is great!
I installed a VA-1A Volts/Amps Insturment [sic] in my 1970 V35B to replace the original analog amp meter. What a great dual purpose digital gauge! Installation was simple and the product is very well made. It goes well next to my SuperClock I installed a couple of years ago. EI makes great products and this one will satisfy the most discriminating owner.
Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
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.
I have been installing avionics since 1996. This was THE BEST wire harness I have ever seen!
Works Great!
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
