Summary: Directional Pad, Two sticks, 6 usable front-facing buttons, two side triggers and two one-direction sliders. Plenty of buttons for todays most demanding games, and definitely by far the most common natively supported controller for PCs. As far as PC gaming goes, this is pretty much all you need.
Summary: It worked for me, no problems with it. It comes with the USB port for computer use as-well, hence why I bought it. Works perfect with Steam and other platforms and games that use a controller.
Summary: I bought this for a controller to use with my steam machine that I built. It works great, and is a solid controller. Well made and definitely worth the money. And best of all, you can use it for your console too if you play those.
