Be warned though. I also purchased on Ebay and it looked very genuine. The packaging and controller felt genuine or very close to it but the battery only lasted about three hours on full charge. The button presses felt slightly less solid but a very good copy nevertheless. I also bought a blue one with the same issue. I don't believe they were genuine as I bought another one from another site for around £42.00 and that was much more like my original controller and the battery lasts around 11-12 hours like it should.
How is the battery on your new one?
Haha! Yeah, well...as you mentioned, they look just like the real thing but when playing with it there is obvious issues, I couldn't play COD as the left analogue stick would move waaaay too much, it was impossible to use. So yes, clearly not the proper thing. I thought it was strange when the ebay ad has been completely removed by eBay, I requested a refund last night and it got instantly accepted. Turns out the company are in Hong Kong despite the location and everything displaying a UK address. Oh well, I knew it was too good to be true. I will just have it on my desk looking pretty.
