It works very well; easy operation.
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.
The layout and quality is impressive.
I really enjoy your products [because they are] simple and easy to use and affordable.
People [at EI] were great to work with.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Very easy to install and directions were straight-forward.
Easy installation.
We chose your product because of the great support and reputation your company sustains.
Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
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.
