The keyboard itself is, in my estimation, but otherwise nothing special. I would have honestly expected more from Cherry. The sharp-edged keys are possibly a matter of taste. I do not like that. Also overall, the quality is no hi-end. But the price is not particularly high.
But:
The Euro is now more than 10 years as cash and for over 12 years as book money. Nevertheless, Cherry has not managed to apply the character.
But even keyboards without the Euro character had more than 10 years ago the @ sign. The sign is used in e-mail addresses, and e-mails are sent a bit longer. Cherry did not consider it necessary to apply but again this character.
Just because you want to use Cyrillic alphabet, it does not mean that one lives in the Stone Age, sent emails and has not heard anything from cash Euro.
But that's not all:
There are missing on the keyboard more 9 standard special characters: {, [,],}, \, μ, ~, ², ³.
On the keys "F", "J" and "5" on the numeric keypad could have been done even shorter dashes or dots for blind typing. But if the letter "A" and "O" of the Cyrillic alphabet are represented slightly distorted by the curved lines.
The LEDs for the "Num Lock", "Caps Lock" and "Scroll Lock" are not [enough] separated from each other, and it gives light from adjacent holes. The light for "Caps Lock" would be the way also can label quietly.
An overall mE very carelessly produced keyboard whose development has stopped well over 10 years ago. Below you would have, for example holder can be integrated in order to fix the cable, as do other manufacturers.
To fix the lower lid four hex screws.
Fortunately, the keyboard is light gray, so you can apply the missing characters with a black pen. That would probably be all in all 11 missing characters. After all, much less than if you wanted to apply the complete Cyrillic alphabet characters + Cyrillic layouts in the pure German version.
Now I could forgive a minimum rating a star. However: The keyboard works; The manufacturer recommends a version with German + Cyrillic is ever offered; the cable is sufficiently long. Therefore, two stars. The keyboard I keep and use them well.
The delivery of Amazon.com was great!
Addendum: After one year of use, the label of the most frequently used buttons will start to fade, the keyboard itself remains functional.
