I had a few days ago ordered this product and does not even have to wait 2-3 days until I've seen it in my mailbox. Thus, the shipment was quick and easy.
Connect:
At one end of the PS2 controller comes in, the other side is in the PS3 or to a free USB port on the PC. That's it. The PS3 controller recognized the immediate and without any problems. What you should consider however is that one represents the PS2 controller on to: Pressing the button positioned in the middle and below is lit a light in red which symbolizes the controller is on.
Operation / "handling"
What many may be of interest is whether you can play just as well with this adapter and a PS2 controller as having an original PS3 controller:
The answer is yes. I use it just in games where it depends on "Aiming" (sighting). Most PS3 controller at 20-25 are atrocious for that matter. There are so-called dead zones that is that you can aim at not so good because the controller is not responding properly. This adapter is however not at all the case.
Price-Performance
Because I need not much to say. The price is compared to "low cost controllers" have the so called dead zones and thus affect the play, cheap. The product fulfills what it promises and the shipping was fast. Strong buy recommendation!
