I ordered this lever into "sold and delivered" by Amazon and the article is not an infringement but an official Sony controller (simply not buy a lot less stick to other resellers third and this applies to all other controllers). The evidence is the instruction in English and French with Sony contact addresses for one year warranty.
The blue color is beautiful and it changes the basic black for about 4 more!
It is identical to the Dual Shock sold with the PS3, just the color that changes.
