If you plan to use this for the PS5 console, it's a great thing to use however if you use your PS5 controller for PC and want to type, not having to grab your keyboard, good luck on getting it to work. On PC, the controller and keypad fight over the Bluetooth signal. I found this out by searching. If your PS5 controller is on, the keypad will not be detected when trying to pair, you must turn the controller off to be able to pair the keypad. If your controller is off and removed, the keypad is on it works flawlessly. Plug the keypad into the controller, it disconnects from PC BT device\dongle. I even followed the steps in the setup sheet included with the keypad. This keypad must be resynced when moving it from one PS5 controller to another. Why... who knows but it is stated in the setup sheet.
I had one instance where I had my PS5 controllers become invisible to my PC. I had started a game up, the controller instantly disconnected and would not reconnect. This was after getting everything "FINALLY" working correctly. Ugh... so either I got a somewhat faulty keypad or just a unfortunate result, I would be skeptical however you might have better luck.
