The reason for the acquisition of the keyboard was natural that black letters on a yellow background are easier to read - for this reason, traffic signs are indeed created in this combination. Indeed, it was for me (wearing glasses and no longer the youngest) initially a relief. In my previous keyboard (white on black) were some signs already faded, and so the visible difference in the first few days and weeks was immense. But what use unlabeled buttons, even if they turn yellow? I am sorry to the other reviews fully agree that speak of the gradual disappearance of the characters: The directional arrow to the left was not even present (but easy to open by logic), and after a few months are "Ctrl", Shift and the letter A virtually disappeared. The rest will probably follow soon. I guess I can use the keyboard altogether for a year, then I'll look for a similar from another company.
