Sharp-looking gauges. [I chose EI because of your] reputation.
Beautiful graphic display, easy to use, perfect automatic dimming!
The tach looks and operates amazing. Extremely accurate.
Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.
It works very well; easy operation.
Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.
Easy installation.
EI tech support is the best.
Easy installation, lightweight solution. It looks good and is easy to use. [I chose E.I. because] I needed to replace my old Hobbs meter. This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.
The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.
I really appreciate the quality of communication about my order. The instrument offers the right functionality (being a primary instrument) in the right form factor for my application.
