This device was a great idea that solved my problems with using external storage and connecting multiple controllers. I experienced a slight lag when using this adapter in my controllers. During the game, they usually switched off or were no longer recognized in ports. After changing my controller's port for the 5th time (to the last port I haven't used yet), my controller was no longer recognized by the adapter, even when I restarted the PS4. I had to remove this adapter to be able to use my controller again, even after several reboots. The same thing happened with my arcade stick and other controllers.
