Provision of non-standard buttons and irrational

If you are looking for a compact keyboard with nice touches and you NEVER use another keyboard, then this may suit you.
However, if you are called to work on other computers, especially if you frequently use shortcuts, this keyboard is CONTRAINDICATED!

To save space, the "left" keys, "Low", "Up" and "Right" are nested in other instead of being isolated as a standard provision. Result: the "0" key on the numeric keypad, usually double size is "eaten" by the "Right" and users accustomed to using the keypad without looking (entering numbers, etc.) that can accumulate data entry errors.
Those who used to use the "PageUp" and "PageDown" will also lose any benchmark since these two keys, instead of being located between the keyboard letters and the numeric keypad (the "Up" being there, logically, above the "Down"), are found between the "AltGr" key and the "Ctrl" (the "Up" left of "Down!")

Errors and yield losses resulting from this configuration both fanciful and irrational my order leads to another keyboard only a week after discovering it.
FYI, I bought the "Logitech - Illuminated Keyboard - Keyboard - Retro illuminated keys, laser - PerfectStroke - USB" * that is virtually perfect for the use I made: standard layout, nice and silent keys, retro -lighting configurable; * Only flaw, very minor, I have not found standby computer key, making it necessary to go through the "Start" menu.
