The trackpads are an interesting new feature for USB (or wireless) gamepads. They provide a bit of extra accuracy in common FPS games when aiming.

The "Dual Stage Triggers" are pretty much the same kind of triggers on the Nintendo Gamecube controllers, as you can hold them down halfway for an analog-based input, and hold it down completely until it "clicks" for a second digital input.

The only thing I dislike about the controller is the Haptic Feedback on the touchpads. For some reason, even the "low" setting seems a bit too much...

The controller overall will take a while to hold naturally in your hands, as the design almost kills your muscle memory for gamepads you use to use, like the PS3/4 or Xbox360/One controllers. If your willing to try something new, or have never used a controller for PC gaming, this may be a nice entry for you.
