This is a set of the bigbigwon Blitz controller and the R100 Pro (wireless converter). With these two, you can use the controller on a variety of platforms such as Switch, PS4, and PC. It has been used for about a month, so there is some wear and tear, but I have confirmed that it works without any problems on PS4. When shipping, I will wrap each item in packing material and pack it with paper to prevent shifting. Please purchase only if you understand that this is a used item. bigbigwon Blitz controller
