Nice feel with small but nervigem driver error

The mouse is really great. It looks chic, feels very good, has nice LED gimmick, good sliding properties and is very precise. The small but annoying catch here is that the additional buttons on the side, not recognized as Mouse Button 4 and 5 and can be adjusted, but only with pre-standard commands from the pull-down menu can be substantiated, and thus for gamers rather "sinnfrei" usable for Officeanwendugen arise as more Options.
A driver or software update yielded no improvement and a direct detection software was not possible.
