These are handheld pads designed use with the Playstation versions of the game Dance Dance Revolution (DDR). Before you blow your lid yelling at the fat kids of today who won't even play exercise-inducing games, hear me out. I used to be one of those DDR-playing kids back in the day, and when I didn t want to spend hours at the arcade and had too much money to count, I enjoyed playing DDR with my fingers. Not only did playing DDR on my computer with the arrow keys improve my hand-eye coordination, it also helped me memorize the songs and beats so that I could further impress the ladies at the arcade. And at $23, these are a must have for any DDR aficionado like the former me (before I took up smoking and learned to love oven-pizza).
