Wired X360 controllers are ass. I love how they're light weight due to not having batteries, but the cable is ridiculously weak.
After a while of picking it up and setting it down/moving it around, the cable starts to tangle up, and the wires in the cable break.
The original Xbox controllers were better tenfold; they had a rigid plastic outer insulation, and then some other weird insulation beneath that. 2 layers to protect the wire with.
