Bought this myself works great.
NOT OFFICIAL but have great reviews!!!
Pros: Really looks and feels like the original product. Almost impossible the see the difference from the real ones. Works very well too.
Cons: None really. The packaging was only some plastic wrap but the product was not damaged so it don´t really matter. The sound in the controller might differ a little bit from the original.
Other Thoughts: Very impressed overall of this product.
Bottomline: Can´t see any reason to buy the much more expensive original product when this one works so well. Will defenetivly buy more of these and recommend to friends too.
