My 14 year old needed it to clean his PS4 controller. One of his. Idk wtf they say one of the little round spinning things(?) stopped working properly and i paid 60 bucks a piece for sooooo new controllers i told him he better get MacGyver on that sucker cuz mama don't buy you one more thing! Disassembled, cleaned, reassembled, now everything is good! Absolutely worth the price! I am not saying that this kit will solve all problems! It won't BUT whatever happened to my son's controllers (which I think were dirty/overdone) it was great.
