Easy Install.
Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Excellent Service. Superb Product.
You folks do a great job. Keep up the good work.
Gauge works great! Very happy with purchase.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
Works great!
Customer Service is far superior… with an excellent record of resolving … technical issues.
Great service. [I replaced/upgraded] unit in aircraft.
I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.
