For all the ways the PlayStation 4 has bested the Xbox One over the past decade, Microsoft has long had the advantage of selling an official enhanced controller. Its Elite series of gamepads come with extra inputs, swappable button layouts, adjustable trigger sensitivity, and other tricks that can give more dedicated Xbox One players a competitive edge.
Sony, meanwhile, has relegated these kinds of accessories to outside manufacturers like Scuf and Astro, whose “premium” controllers have largely been fine, but they can’t quite provide the feature set or sense of harmony that a full-on first-party pro controller could.
The DualShock 4 Back Button Attachment isn't quite that. It doesn’t have “hair trigger locks,” interchangeable joysticks, or many other special features. But it does add the most immediately useful piece of any enhanced controller: two mappable rear paddles, which can duplicate any pair of buttons on the DualShock 4 proper. The idea is to give you quicker or more convenient access to inputs you frequently use in certain games. Because the device is so minimalist, it’s highly affordable—at $30, it’s multiple times cheaper than most pro controllers, even factoring in the cost of a DualShock 4 itself.
