You have many ways to determine if this card is for you.
1. read the comments. many of the comments are pretty clear and detailed. Wait longer and you will see more comments. after time, you will start to know the names of the people commenting and learn what each commenter likes and then you can "understand" the comment better.
2. Ratings are misleading. Some will give low ratings for one detail even if the rest of the card is great. and vice versa.
3. isworkshop.eu is a page with other details. This has too much information. I can't describe it all. (it's a good thing, but you have to see it for yourself.)
there are others, but this is a good place to start.
