Easy install, good product. [I chose EI because of my] experience with [the] product.
Good support when we called with particular questions with the initial setup. We liked the functions and the price.
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
Great service for Electronics International. Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.
Easy Install.
Always built well. Always dependable. Been using & relying on EI equip for over 35 years!
Your customer support is far superior . . . . I appreciate all your help.
Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
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.
