Query: Fast shipping. Works perfectly.

Had the old white play n charge from my old x-box but when I upgraded to the Slim my black controller looked weird and my buddy had to use batteries on my other controller. NOW I have my black play n charge with my black controller and my roommate plays with the white one and we also now save on those &*$#%@! batteries. Thanks again Amazon for the discount and amazingly fast shipping!!It has now been three months and this product is still working as intended. All I do is plug it in to my console and the controller when the charge is low.I am also going to mention how awesome the shipping speed is on Amazon since it has yet to disappoint me :p
