Awesome Tech Support. Like the functions it supports and the fit and look in the panel.

Brian M. from California
Mooney M20F Executive 21

The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.

Charles M. from South Dakota
Cessna 150F

Works Great!

Charlie M. From Texas
American Champion 8KCAB Decathlon

The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.

Daniel N. From California
Cessna 175 Skylark

Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.

Your guys were great at answering all my questions . . . .

EI’s team is great; you guys are the best.

[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
