Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
Straight up install no issues. Works as advertised!
Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.
Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
Excellent Service, superb product.
I have worked with your products before and I like them.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
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.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
The reviews online were very good. Customer service has been great.
