I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.

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.

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.

Good value and functionality. I’ve used your instruments on multiple aircraft thru the years with no issues. These are a nice upgrade over the original instruments in most older aircraft.
Great service. [I replaced/upgraded] unit in aircraft.

Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
EI tech support is the best.
I installed a VA-1A Volts/Amps Insturment [sic] in my 1970 V35B to replace the original analog amp meter. What a great dual purpose digital gauge! Installation was simple and the product is very well made. It goes well next to my SuperClock I installed a couple of years ago. EI makes great products and this one will satisfy the most discriminating owner.
