saves money when you buy this sony product from wal-mart two-fold. Wal-mart sells this product cheaper than any other i researched before my purchase. Secondly, this is a two pack with longer cord lenght than the factory PS3 cord. Great for big rooms with these longer lenght cords i believe and small rooms you could use the controller and never have to unhook the sony charge cable. You will end up getting sony product for a sony product (not after-market ?) and as mentioned you can buy this and get two cords cheaper than you can buy one for. suits me for my purpose.
