Negative, probbably a lower "USP"/quality grade, and again lower quality control. I do think that the DK and Loef. have a decent reputation, but with those companies i'm always worried about the 'ol "bait and switch". When they first come out they are on the line, and test good-but once they get a rep they could start making a lower quality product. Not saying that this is the case with those two-just a concern
