This NumPad I have my partner paid for our netbook so that they finally halfway comfortable coming to the French special characters again (you remember from PC: Alt key hold, enter 3-digit code on the 10-key and enjoy special characters). The numpad is - because of the lack of 10-button keypad on the netbook - to use this well, however, the keyboard offers the more additional input from "Enter" or "Return" before the character appears. The cable is not as indicated here on several retractable. The unit has three extra keys, one should call the calculator well, the other two buttons are incomprehensible to us. All three keys have with us (Windows XP) has no function.
Conclusion: For the desired purpose useful, price OK, a star deduction for lack of guidance and the useless keys.
