The quality doesn't seem particularly great for the SM bought decks. For instance, for a foreign language deck I'd like to see images and native pronunciations, preferably from multiple speakers. For a chemistry deck I'd like to see 3D representations of molecules, preferably in multiple manners (ball-and-stick, spheres, etc), even better if the flash card allowed for rotational viewing of the molecule.

I definitely wouldn't buy any of the decks I saw on SM.
