Ok, will post here.
Having a good experience with PYC 11s silver version chains I went for another PYC 11s but this time dlc black version. Yes, it is still noticeably cheaper than KMC counterparts. I have never had dlc chain before so I do not know much about the coating quality of these chains.
Picture below shows PYC dlc taken out of the packaging, speaking of which, unlike the silver versions (I buy from ebayer from Ireland) this black PYC did not come in original box. Unless original box is completely black without any descriptions whatsoever. Anyway, looking at the coating it does not look good, especially the edges of the plates and rollers. To me it looks like really poor quality.
How about your dlc chains, do they come with the blemishes as well or they are perfectly coated?
Just for the records, this chain did come from a different source than mentioned above Irish connection.
