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.

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…
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.

Love the look and having every piece of info in front of me… Better price and look [versus competition].
The CGR-30P is working great and it’s an outstanding addition to our avionics package.
The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
