I have been told that if you get certain electronic goods like this it only means that the goods are not "official imports" meant to be sold in Switzerland, i.e. they are grey imports from Germany or elsewhere, which could explain why they are so much cheaper. Thus the warranty may be affected although I am not quite sure how. Whether what I heard is true or not I can't say because so far I have never had problems with the goods I have bought on-line.
