EI’s products are the only ones we recommend to our customers.
Great service. [I replaced/upgraded] unit in aircraft.
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
We love our MVP-50P w/ its crisp, intuitive display and ease of operation.
Beautiful graphic display, easy to use, perfect automatic dimming!
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 customer support. My A&P installed a CGR in a Comanche and liked it.
EI shines in providing excellent customer support and its products are reliable, affordable and of high quality.
[Customer service] is great!
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.
[I chose EI because of its] Reputation and value.
