I bought this for my son to use with his PS4 and charge his two Dualshock controllers. It works exactly as expected. Not sure what else to say about that - you turn on two controllers and they charge. At first my son had some trouble placing the controllers correctly for them to charge, but the lights indicated when the controllers were charging and my son eventually learned how to place the controllers properly. Not only do the controllers charge well, I like that the controllers are mounted on the charger so they're easy to find and don't get lost, stepped on (or eaten by a dog).
