This product does what it is supposed to do, namely hold the controller in your hand. But I had two big problems with it. First, the keys are small, but that's hardly the manufacturer's fault. It was designed to be fixed with a controller. So of course small. However, if you're playing a game like Final Fantasy XIV and need to type fast, then this keyboard isn't for you. It takes too long to print anything on it. Because it's too small, you can accidentally press the wrong button. Secondly, some keys need to be pressed in order for them to work. On my keyboard, it was the letter "e" that I had to press harder than the others. I gave this score because it does what it's supposed to do. But if you need to type fast on PS4, your best bet is to get a Bluetooth keyboard. It makes typing easier and faster. (Also cheaper.)
