I like how the kits ship with everything needed for install and the wire labeling was very helpful.
I have never had an issue with any EI products… it looks fantastic on the panel.
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
EI tech support is the best.
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.
Your customer support is far superior . . . . I appreciate all your help.
Very easy to install. Harness is clearly marked. Instrument worked first time. The instrument is intuitive and easy to use.
Very complete and thorough packaging. Well-prepped wiring harnesses. Quick and efficient turnaround time. Great communication throughout the process.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
