Excellent installation instructions [&] recommend[ed] by others.
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.
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
Outstanding support. From the friendly demeanor of whoever answers the phone to all the way to [their sales representative]. Your CGR-30 series is superb.
I was able to try out the CGR-30P in a flight school plane. I was very impressed with the ease of use, visual quality, and information provided on the main screen… I feel it will pay for itself in fuel savings, and extended engine time before overhaul.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
Safety and simplicity!
Met all my requirements; great support.
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!
