Target missed.
Lt. Description is the number of special keys identical. What is not mentioned anywhere: button below the scroll wheel is not configurable but is fixed used to switch the mouse resolution (who needs something !?).
In practical operation on the Mac mouse is detected not always clean in the wireless condition at startup. Many experiments have shown the me that the mouse is recognized only halfway safe when switched at startup in the charging station is (certainly "not Mac-like").
Was also known that the battery life is not too huge. What the hell, one can continue playing with the USB cable when the juice is all -> No way. Mind you the Mac! (PC I could not try) Mouse battery reconnected all, USB cable after about two hours, mouse running again but it follows utter confusion because the mouse ran only as a normal mouse without special functions and game integration.
For me, at the end of a no go too much.
