I bought two of these cables from discountextras. I immediately noticed that the wires are much thinner than other USB cables. Despite it being advertised for the HD2, neither of them worked with the HD2 - it did not recognise being connected to the PC and it would not even charge. On removing it from my HD2, I noticed that the metal part of the micro USB socket could be pushed in and out of the black plastic cover, the same with the wire. In other words, the metal plug and wire connection was loose inside the cover. The same applied to the second cable. The issue appears to be with the cables; other cables from discountextras were good.
