Review on 🎮 ZFY PS4 Bluetooth Wireless Gamepad in Orange: Compatible with PS-4/Slim/Pro/PC/Android, Speaker, Touch Panel, High Sensitivity Joystick by Jennifer Schreier

The buttons seem to work well but the joysticks are very "loose" so I wouldn't recommend it for FPS games (no matter how I regulated the game sensitivity settings). This works for something like Mortal Kombat, where I use a D-Pad instead. Also, the battery charges fairly slowly and doesn't last very long, and for some reason my headset mic is quieter than my other controllers.
