+++ For the better:
The mouse is thanks to ergonomic waist with a textured surface very well in the hand, and the weight suits me. The additional buttons are easily accessible without disturbing. Radio contact is good, what in between at 40 cm distance and without objects was also to be expected. The ability to switch the Scrollradlagerung - rasterized or unrestrained - I find super and use both depending on the application.
/// General:
The extra buttons on the mouse I hardly use. And since I'm still working with Windows 7, the Windows 8 modifier key first pointless, but not quite, anyway: Without the Logitech software to install the special keys are assigned as follows:
Left, the front = [Windows]: Open the Start menu
Links, rear = [Windows] + D: Minimize all windows
before the scroll wheel plus mouse movement to the left = [Windows] + [Tab]: Calling Flip 3D application overview
Scroll to the left tilt = [Backspace]: Previous website
Scroll to the right tilt = [Shift] + [Backspace]: following website
- - - For the worse
What I do not like so much is the mat material of the palm rest surface: First, it is nice to look glossy / greasy from the first use at the contact points. This could have been solved differently ...
But my biggest complaint is the lack of precision of motion detection: No matter what surface I mouse use (light or black wood veneer, spruce board, white paper, velvet gray mouse pad) mouse while working principle, but a pixel-accurate is not possible. Because no matter how slow I move the mouse, the cursor initially would not touch and then jumping immediately but several pixels. That makes me sometimes for frustration in strategy games and image editing, like users but might not notice.
