[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
[Customer service] is great!
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.
Works great!
Great company to deal with. Excellent customer service. [I chose this E.I. instrument because it’s] simple and easy to use.
I have seen your products in other aircraft and have seen their reliability.
Great service and support for great products!
The tach looks and operates amazing. Extremely accurate.
Beautiful graphic display, easy to use, perfect automatic dimming!
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 equipment is fantastic, very intuitive, and easy to use.
