Theoretically, a good keyboard - virtually useless

The keyboard is the feel and appearance to very nice. The keys have a pleasant pressure point and are relatively quiet to operate. A bit annoying is the small F1-F12 and ESC buttons that can be pressed harder and are not as well suited for the more common Einsatztz.

Most annoying though is the unreliability of signals. It happens very often that the signals from the keyboard are not only delayed or sent to the recipient. Since then helps often, the USB receiver off and insert - no matter which USB port I have tried it, the problem occurs in Windows 7 and Vista on both, directly after a new installation. Even in direct line of sight. So unfortunately I can only advise of the otherwise beautiful keyboard.
