Awesome Product! Great product and fantastic support!
Great tech support. Someone always answers and gives accurate concise information.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
I like how the kits ship with everything needed for install and the wire labeling was very helpful.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
[I chose EI because of its] reputation [and the] quality and appearance of the instrument.
Very nice product, giving a real advantage on fuel management.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
Great service for Electronics International. Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.
Great product. So easy to read compared to the originals.
Your product didn’t feel cheaply made. Overall much better quality with the bezel and buttons and knobs. Also much easier to navigate and add fuel.
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!
