Why are these PS4 controllers so cheap?

Can anyone tell me why these controllers are so cheap? Is the page fake or are the controllers just not original? Thank you

They are not original

Okay thanks but do you mean they work?

Are not real, you can recognize by the symbols for X, …

Yes they work

At least they should

Replicas from China are certainly. It costs half and is probably only half as good.

They are extremely expensive, considering that you can get China snot cheaply clipped together.

I almost thought, thanks.

Are not real and whether they work without problems is also questionable.
