Late reply, I know, but I wanted to give my 2 cents on this one:
I own one of these controllers. I actually had one of the earlier models. You get a few goodies with the controller.
My findings thus far:
- Razer QC must have struck on the first one I had; about 2 months in, the R1 trigger caved into the controller and I had to RMA it. No problems with the 2nd one thus far.
- The A/B/X/Y face buttons are tactile (read: clicky) and backlit. (You can turn the backlighting off, FWIW.) I presume they might have a Kailh switch in each; it's been hard to find out further information on that. IMO, this is the best part of the entire setup.
- The rocker buttons are a neat idea, but most PC games I own don't even recognize them (let alone use them). FWIW, you can map the extra buttons to act as face buttons and so forth, which some may like.
- The onboard memory allows you to switch between 2 profiles. Best part: you don't need Synapse to make use of this.
- The D-pad buttons are independent, rather than being mapped to one rocker, which is nice.
- The default sticks have an odd grippy texture to them, and you get a couple of green rubber grips to lay over them. The grips feel nice, but they also start to disintegrate and leave crap in your joystick slots, which is bad; they're a pain to clean out.
- Not wireless. I'm perfectly OK with that, but if you don't like braided cables, beware.
- The bottom of the controller has a headset/mic jack, if you use that sort of thing.
Aside from the tragic mechanical failure on that first one, I'm pleased with this second one overall. If you're willing to stomach the ~$80 price tag, I'd recommend it over the standard XBox controller (those never quite sat right with me for some reason...)
