GG Bran Scandinavian Crisp Bread

I was reading an article on how to survive at parties and they mentioned this Crisp Bread as a low calorie (12 per slice) way to fill up with lots of fiber.

Has anyone tried these "crisp breads"? Do you like them? Are they worth it?

It seems that they are only sold in the states and are apparently sold in cases for $65 a case! I would like to try them but they look like another cardboard snack to me...
