Product Description
The color values of Opteka Digital Grey Card set have been tested under varying light conditions and show a high degree of spectral neutrality. Using the industry-standard X-Rite spectrophotometer, LAB values of L* 63.8, a* -1.6, b* -0.4 are measured from the surface of the grey card under D50 standard illuminant. For optimum color correction, the black card achieves truly deep blacks (RGB 16,16,15). The grey card displays superior spectral neutrality with measured values of 162, 162, 160. The white card has a tested RGB value of (220, 224, 223). All three cards have excellent uniformity across a range of light sources.

As you can see from the item description, you get three cards in the set; one black, one white, and one grey. I realize I could use the black and white cards, but the reality is that I'm only ever really going to use the grey one. Still, that's just fine with me. At that price, even if it had been just the grey card, I'd be satisfied. But it gets better ...
All three cards are exactly the same size as a credit card. So if you're like me and you're only going to use the grey one, that's perfect because you can just slip it in your wallet where a credit card would normally go and it fits perfectly. You don't have to bother with the neck strap. But it still gets better ...
The neck strap that comes with these cards is actually really nice. It's got a quick-release plastic buckle on the end. It's a pity to leave it lying around a drawer if you're carrying the card in your wallet, so you can use it for tons of other things. If you work at a place that makes you wear an ID badge, it'll work for that. If you want to carry your car keys around your neck, but still be able to quick-release them for driving or whatnot, it'll work for that.
So, to summarize, you get the grey card at a great price (which is probably why you're buying this anyway). You get a black and a white card that you're probably not going to use (no biggie). And you also get a pretty nifty neck strap that you can use for something else even if you don't use it to carry around these cards.
The only criticism I have is that the grey card comes with the company branded logo on a sticker on one side. Given that it's a small card, that sticker is pretty big and it means that you're going to be using the other side of the grey card unless you peel off the sticker ... except that the sticker is made of the kind of stuff that doesn't come off nicely. If you've got a bottle of Goo Gone, you'll be all set.

These color cards are only a thin veneer of color on a white core. Don't even think of keeping loose in a pocket. My cards are already transfering colors between cards from slight rubbing together. The gray card has also picked up a brown tint (making it useless for white balance) by simply sitting next to my leather wallet--and try as I might, I cannot clean this tint--it is pemanently stained it seems.
White card has black splothes that won't come off, black card has white showingvthru from wear, gray card stained. Pretty sad--especially since I kept these iny pocket just once.

A very helpful photography tool for setting white balance & compensation exposures. Glad I got it. The compact size (the cards fit in my Tamrac 515 camera case) and ease of wearing around my neck on the provided lanyard means I carry the cards with me anywhere I take my camera; without inconvenience, bulk or a lot of extra weight. It's a great product design. Glad I bought the set - it's useful to have the white and black as well as the 18% grey cards.

Good product, over priced
These do what they're supposed to do. But don't expect any miracles. For the price, i would have expected a little higher quality card.

2 years since I ordered this set and it's still my primary mode of white balance on-location. Keep the cards on the provided lanyard in my bag and wear it for the entire shoot.
