This is not unusual though.  Microsoft and Sony both are quite particular about allowing third party companies to mimic the technology they utilize in their own peripherals. Rather than utilizing the Bluetooth technology, the 2.4Ghz Logitech controller uses a handy mini-receiver, which can be placed in the PS3's USB port.  Once you add two AA batteries into the back compartment, you're ready to play.

One point of interest is that while the controller does contain rumble technology, the motion-sensing functionality seems to be missing in action. That's rather an odd choice considering that the first crop of PS3 games do not support rumble. If any do in the near future though, you're ahead of the curve if you have this gamepad.

I believe in trial by fire, so I played long sessions of Stardust HD, the PSN downloadable shooter and the mind-numbingly difficult Ninja Gaiden Sigma.  In both instances, the Logitech controller performed as I expected and was responsive in all situations.  Stardust HD requires quick decisions and even quicker motions, utilizing both the left and right analog sticks. The controller was up to the challenge though, and allowed me to plow through plenty of asteroids and enemies.

As Ninja Gaiden veterans know, you live and die on whether or not you're able to perform analog motions quickly enough to unleash decapitating combos.  Again, the Logitech controller didn't fail me at any time, and my own failures were a result of my lousy decision-making.  In addition to the analog sticks and face buttons performing beautifully, the shoulder buttons were equally responsive and allowed me to block enemy attacks with ease and evade certain death.  While the Logitech Cordless Precision Controller and SIXAXIS have much in common, the D-Pad is markedly different.

Sony continues to utilize individual buttons for up, down, left and right.  While this design has served gamers well over the years, there are some games where being able to quickly execute circular motions on the D-Pad is the difference between dominating the competition and getting your ass handed to you.  Logitech has thankfully continued to employ the disc-shaped pad, which is much easier to use for games which require that level of control. All things considered, you're getting a solid gaming controller at a reasonable price, albeit not as feature rich as Sony's SIXAXIS.
