Well, i returned my Cordless Precision and exchanged it for Nyko's gaudy AirFlo Wireless.
I can now confirm Nyko's iz MUCH more better than Logitech's. At nearly the same price point, you get a controller that not only feels more comfortable (and akin to the S-Type), but you also get some nifty fans (and uh, a miniature arcade stick).
It may look big, but it's actually quite light. HIGHLY RECOMMENDED (official controller replacement? Yes!)
