What you're looking at here is an early PlayStation controller for the original PlayStation console. It's like the Dual Shock pad, except there is no rumble feedback and it doesn't have the two analogue sticks.
The pad (SCPH-1080 to give its model code name) is a comfortable product to hold in your hands. The D-pad, Start, Select and face buttons are all within the reach of your thumbs; as are the four shoulder buttons with your index and middle fingers. The downside is without the analogue sticks you don't get the precise control for games like Gran Turismo, and in the case of Ape Escape you cannot use this pad at all (it's Dual Shock only for that one).
It's an OK controller to use, but the Dual Shock controller is the number one choice for anyone who still owns a PlayStation or PSone console. This is more of an antique for retro gaming collectors to have on their display shelf. It's a cool antique, mind.
