Easy Install.
Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
Great product. [I chose EI because] you have no competition.
I have worked with your products before and I like them.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
Installation went great. The Fuel Flow is dead on.
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.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
This is the third EI instrument I am having installed in “Lillybelle .” I am impressed with the ease of operation, the affordability and the accuracy of each of these instruments. For years I trusted my life to 50+ year old gauges. Now I don’t have to. What a relief!
MVP-50 is a really great product
