I ordered this on December 3rd 2015 (I took my time to use the keyboard properly). She arrived on December 10th, although she was supposed to arrive between December 23rd and 26th. The keyboard is generally solid. The keys are made of very soft rubber, they have a soft touch and do not click like a normal mechanical keyboard. I wondered if I had pushed the button or not. Each button works well with most PS4 input functions. The keyboard is connected via the audio jack. This will make the PS4 assume you have a headset plugged in. To counteract this, change the output in the Sound and device settings menu to output "Headset" as "Chat Only". The audio jack on the keyboard itself works well and connects the headset to the PS4 without any noticeable issues. In summary, the main function of the keyboard works well as a real keyboard, and the sound transmission works when using a headset. The only issue I had was the soft feel when typing.
