In flight for 1.5 months, there was no stench from the wire. The microsoft hologram is present at the back, the screws are ordinary (not torx), it was ordered in idea74 for 1430. As for the hex screws, I specifically looked through a number of online stores, in many of the screenshots of the rear view of Joy the same thing (ordinary screws). So I don't think you need to worry about it.
