+ The keyboard seems solid processed and speaks to keystroke good. The keys have a relatively soft pressure point, what suits me personally. When you tap shaking and klackert nothing in heavy stop the keypad in the center seems easy to springs.
+ Commissioning works fine: USB adapter plug and off you go. However, the included software on a CD is required for the additional functions of the keyboard.
+ At the curved keyboard form you get used quickly and then saves my impression compared to a standard keyboard the fingers significantly.
+ The support surface for the finger is rubberized and puts his hands when writing enjoyable.
+ The modifier keys are arranged intuitively and most of them are very useful. Among other keys for quick access to common programs (word processor, spreadsheet, calculator, browser, e-mail, calendar, etc.) are present, which are controlled by "Fn" + F keys. These buttons can be individually configured via the included software, which works without problems.
+ The supplied USB wireless adapter detects other Logitech products, so that only one USB connection is required. The wireless feature also holds otherwise definitely delivers what it promises: keyboard signals were detected reliably over a distance of at least 7 meters.
- The processing of the additional keys could be valent, the buttons wiggle in their version and have a very spongy pressure point. Since it is likely less arrive at fast typing in rapid succession at the modifier keys, but a lack verschmerzbarer.
- The pity is that the on-off button on the keyboard is attached to the bottom.
- Light deduction is also available for the Software Setpoint. The menu could there be much clearer, some of the options tell not at first glance. The software automatically detects all available Logitech products, ignoring the previous system settings. Mouse, Headset & Co. must therefore be re-adjustment. An "opt-out" of this function I could not discover.
Overall, I can issue a strong buy recommendation.
