The following paragraph should be noted:

In order to be able to offer you our return guarantee in the future as well, we ask you to try out the goods just like in a retail store and to return the goods completely, in their original packaging and in unused and undamaged condition to us.

Otherwise you have a right of return of 30 days.

If you send that back immediately, that's no problem.
Also had an ACER laptop, which I sent back after 5 days because my keyboard was "too cluttered".

Returned receipt with explanation "Reason for return" attached… That's it.

Reset to factory state, then you can send it back.
