Negative to mention the one hand, the short disconnections and less accurate control of certain keys. The L and R buttons are 2 MMN eg not as accurate, but have a better resistance. In general, the buttons and sticks have a good feedback Pack and feel good and high quality.
For games like FIFA 14, Assassin's Creed, several Star Wars titles and Prince of Persia (anything) certainly perfectly adequate.
The disconnections are really just very short and have not been disturbed. I can imagine that the udgl but certainly could represent an unacceptable problem in racing games. To this end, I can not report any experience, because I do not play (and my son) such titles ...
Conclusion:
For the price an excellent quality. Some things such as grip and resistance of the pushbuttons are even much better than the original! Others are bad, but not really bad for me.
The parts you see what is likely an original PS3 controller actually cost.
Thank CSL for alternative!
