We liked the price and the reputation of your company.
Good to go! Excellent instructions and easy install. Outstanding instrument!
We’ve worked with EI for years and love the product and support always received. Quality & dependability.
Currently have multiple EI Instruments in our aircraft. Quality and reliability are key.
Great customer support. My A&P installed a CGR in a Comanche and liked it.
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…
. . . the kit looks very well built and the company I fly for . . . has had a very good experience with your products and your customer support.
Nice bright display.
Sales reps have been very friendly and helpful.
Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Works Great!
