Straight up install no issues. Works as advertised!
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
Great tech support. Someone always answers and gives accurate concise information.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
Excellent installation instructions [&] recommend[ed] by others.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
Sharp-looking gauges. [I chose EI because of your] reputation.
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.
The equipment is fantastic, very intuitive, and easy to use.
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.
Love my new engine monitoring system.
EI tech support is the best.
