We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
After enquiring through (one of) your dealers and calling EI directly it was clear that you provided good customer service and would likely not drop the ball on tech support, and so far I have been right.
Nice unit. EI is the best!
The tach looks and operates amazing. Extremely accurate.
. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.
Looks great. Works 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.
