The AW.2's primary purpose is to act as an alternative to Nintendo's first-party Nunchuck. Everything the standard peripheral does, this one does. What it also offers are some flashy lights (in our case, blue), and a spring-loaded retractable cable to keep it safe when not in use.
Unlike the AW.1, this AFTERGLOW product doesn't rearrange any of the buttons. Granted, the Nunchuck only has an Analog Stick and two buttons, but PDP apparently decided they were already in the most effective locations. I will say though, the Analog Stick's head seems to be a bit smaller than that of the standard Nunchuck, and the buttons seem to have a bit more click behind them... but then again, it could be that my first-party versions are just old and those buttons have softened a bit over the years.
The retractable cable pulls out of the base of the AW.2 and clicks as it comes out to keep it from slipping back into the spring-loaded mechanism. When you are ready to pack it up, you simply disconnect it from the Wii-mote, press a button just above where the cable comes out and the wire zips back into its protective covering. This isn't a new mechanism, but I can't recall any other controller using it before.
