Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
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.
A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
Works great!
Nice experience working with [sales]… to configure my gauges.” Reason I chose EI? “Past experience with EI.
Responsive customer service, kudos to [customer service].
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.
Looks great. Works great.
[Customer Support was] very responsive and helpful. [I heard about EI through] advice from others. Just about everyone I asked about the CGR-30 loves it and your company.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
I have seen your products in other aircraft and have seen their reliability.
