Your products always work great! Great customer service and a quality product that we have used for years.
Awesome Product! Great product and fantastic support!
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!
Great product. So easy to read compared to the originals.
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…
I have never had an issue with any EI products… it looks fantastic on the panel.
Phone service for ordering was quick and easy. Shipping was quick.
Great product. [I chose EI because] you have no competition.
Your (customer) service is excellent!
EI tech support is the best.
I installed a VA-1A Volts/Amps Insturment [sic] in my 1970 V35B to replace the original analog amp meter. What a great dual purpose digital gauge! Installation was simple and the product is very well made. It goes well next to my SuperClock I installed a couple of years ago. EI makes great products and this one will satisfy the most discriminating owner.
