Your (customer) service is excellent!
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.
Straight up install no issues. Works as advertised!
We have other EI products currently and have always been satisfied.
I like the 3.125″ format. Plus there are no hidden costs of probes you have to buy later…
Great product. So easy to read compared to the originals.
I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
Customer service always quick and easy. [I chose E.I. because of] price and being recommended by friends.
Great service. [I replaced/upgraded] unit in aircraft.
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
Responsive customer service, kudos to [customer service].
Great product, frees up space
