In this video, I will do a quick comparative review of factory engraving versus importer engraving.
The difference is that the importer applies letters to a ready-made universal keyboard, where large English characters are located in the center of the key, and there is less space for applying a letter in another language, so the letter is applied in a smaller font and is located at the bottom right of the button.
Factory engraving involves applying letters according to the rules, that is, the letters have the same size, font and are located symmetrically on the diagonal so that it is visually more favorable for the user.
Considering the high price of the Logitech MX KEYS S keyboard, I believe that the engraving should be of higher quality.
