Don't you just hate it when your trusty old controller starts failing on you? It comes on slow at first, maybe the right bumper doesn't click as easy or the right stick is just a pinch loose, but then nothing works on it anymore. Toys 'R Us has got replacements ready for you at $15 less the usual cost. They ain't fancy, but they'll get the job done right.
