Very good! Since Sony could abschauen what.

The pads functioned immediately after the plug properly.
What disturbs something that is both USB spots are occupied. But the circumstances that an original PS3 controller about four times of the fingers here costs can, seen from some minor inconveniences away ;-)
Two of these were also tested Controller with 4 Original PS3 controls. There were no incompatibilities or interference.
Here I had probably lucky that I got the 2 itself does not spark between them. Other Rezensoren had apparently here before problems ...
I play with the CSL controls mitlerweile even better than the originals. The CSL are much better in the hand. the surface is significantly more stringent than the original, the hands sweat less.

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!
