Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
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.
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.
Phone service for ordering was quick and easy. Shipping was quick.
We have other EI products currently and have always been satisfied.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Nice bright display.
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!
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.
Great… price [&] support
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
