I bought two packs of these on two separate orders, and they are both of quite crappy quality. Many of the connectors are bent, and they mate very badly to the sockets. This easily gives noise when touching them, and you can never be quite sure that the connection is good as they often do not lock properly in place. I also worry that they will damage the sockets after a while, as it just "feels wrong" when connecting them.
For example the ones from Doepfer are a lot better, have no mating/locking issues, straight connectors and are around the same price even if you buy 6 of them separately.
