Coupling:
Under Windows 8.1 32-bit I had no problems, the mouse to be connected to the tablet. Under MacOS 10.8.5 coupling proceeded just as easy.
Function:
I can not say anything yet, but I have the mouse is not long enough about the battery life. However, there is a separate on / off switch, which is to save energy already practically. Of the main buttons there were, three, left, right and middle mouse button (scroll wheel). In addition, there is a Windows button on your mouse button to start a call setup to the computer with the mouse.
Honestly, I am beginning to fight with the battery compartment (did not understand right away how this will work out). With feeling and patience we went it: D.
Unfortunately, the M557 jerky at times, where it is not on the base (table top) is apparently, but the mouse appears to other Bluetooth devices in the area not so well with tolerated. With no other active device the M557 is going well. I use the mouse yes especially for Office / Internet, less for games (I prefer my wired G600).
My Conclusion:
Useful mouse, the Hakeln (BT-interference?) And the PL ratio lead to four stars. In mice, I am very critical and have been a few of them by (who have not been good for me so).
