Very Disappointed with this product. From it's description and price I expected a few dozen cards with a lot more info on them and there are barely more than dozen in the set. The product itself is very nice and somewhat informative. Although you could just look the same info up on the internet and print it on a word file for yourself. I think it is hardly worth the price they are asking.
If you want any of these, I'd wait until they figure out that they should include all of these in a bundle for just the one price instead of trying to gouge the customer into paying this price several times for only a few cards at a time. After all, it's your money and you are the one who will also be paying for the ink and card stock to print it on.
