Has anyone ever used one of these? Are they far better than the gray card?

Ya, the keychain version is an ornament. Like back in the day when big wall rock climbers kept a #1 RURP on their keychains.$19 for the keychain version
A decent grey card will have an incredibly matte surface recording all light that hits it neutral. That's exactly what you want in a grey card.ExpoDisc vs. gray card:
Reflections off of a gray card might affect you color reading. With ExpoDisc, you don't need to watch out for the reflections.
You could buy 10 cheap grey cards for the cost of an ExpoDisc, or about 3-5 very well calibrated ones.ExpoDisc is accurately calibrated, and it does not shift in color over time, like some cheaper gray cards.
After spending $100 (less than the cost of an ExpoDisc) on a colour checker passport I get a GretagMacbeth colour checker chart, a white balance adjustment chart, and a quality grey card in a tiny conveniently pocket sized hard ABS case. This has already survived one roll down about 20 stairs.ExpoDisc is more durable than the majority of gray cards since its optical materials are enclosed in an anodized aluminum ring.
