A pretty good deal I think. Maximum two per customer (Easter sale)
"This newly announced part of PlayStation Move is a one handed controller that further expands the interaction that you can experience with PlayStation Move titles.
The sleek design makes the Sub-controller easy and comfortable to use. But for those who still enjoy buttons, the Sub-contoller comes with an analog stick and directional buttons to move.
Please note, this controller requires either a Playstation Move Starter Pack or Playstation Move Controller to function."
