I really enjoy your products [because they are] simple and easy to use and affordable.
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.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
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!
You folks do a great job. Keep up the good work.
Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
The R-1-6 is a great instrument. [I chose EI because of] quality.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
