My review of the Razer Onza TE (Tournament Edition):

Controller feels good in the hands. Feels like a normal wired xbox 360 controller. The USB braided wire is 15 feet long and has a quick disconnect incase someone trips over the cable. The buttons themselves light up, and feel a lot easier to push than the regular controllers. They make kind of a "clicking" sound when you press them, but hardly noticeable when you start playing.

The 2 extra bumper buttons are programmable, but take a little getting used to because they are right where the original bumper buttons are on the 360 controller. You can remap them to any key you want to. Programming the buttons is easy and just require you to press and hold the "Remap" button on the back and press the corresponding key you want it to be remapped to. The remap display shows what the new bumper key is rebound to. I found myself remapping both buttons to the RB/LB to play CoD. I havent tried it...
