While we didn't have occasion to test the programmability, we can definitively say that the Sabertooth's other functions are just as solid as with the Onza.
In the company's second Xbox 360 controller -- the Sabertooth -- Razer's focusing on the tournament gaming crowd rather than simply outfitting its Onza with "Tournament Edition" specs.
Shallow, squishy shoulder buttons akin to those on Sony's DualShock 3 compare poorly to those found on the current Xbox 360 controller as well as competent third-party equivalents (the Razer Onza, for instance).
