Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
Love my new engine monitoring system.

Your customer service is excellent and your products are top quality!
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.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
It works very well; easy operation.
