Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
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.
Easiest company to deal with and an awesome product! Price, Certified for Primary, and Features.
Great product. [I chose EI because] you have no competition.
Best sales team.
Good equipment at a good price. I have used your products before and have had great success.
Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
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!
[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.
