100% ok..??

[PG]

What do you think of this card on ebay (look at the place where the battery has been): item 8772006339
And here is another with missing oscillator: item 8768919490
How can the sellers say that they are 100% ok..?

Well, i must admit that German is not my native language either..:-)
But surely "Karte in 100% funktionierendem Zustand" and "einwandfrei" means that the cards are in perfect working conditions?
My apologies to the sellers and correct me if im wrong.
Of course the defects can be seen in the pictures but is that good enough?
