still in need of improvement

compared to the previous mice, this is really smart by design! the receiver setup is very compact and can be stored this time very close to the mouse. in the old models, he was simply clicks range and fell during transport often again.
also finally got its own on / off switch donated this mouse. so you can save an additional night in the batteries.
The great thing is that this mouse really works on all surfaces. the range is also ok, but still has not managed to improve the range of Logitech with obstacles, the mouse begins just like the predecessor to bucking, once you have one leg or the like between the mouse and receiver. it is sufficient if the notebook shot takes on, and the mouse next to lying on the sofa. it always comes back to stuttering and dropouts. very bad it is in interference with a wireless network. the mouse is no longer usable, for example, when copying files via WLAN from one computer to another. they no longer responding.
also is the pressure point very uncertain at the wheel button. If you want to use the wheel as a middle mouse button (for panning, etc.), so you have to press some very strong, although the pressure point is reached long ago. so it happens often that one press instead at the fixed scroll or page scrolling function is activated. so I had to turn off the driver this feature. Too bad, because otherwise this mouse would be really perfect.
