So I must say after reading so the old model already had, the new is still besser.Das noise from the scroll wheel is totally leise.Und what I also find super: There is here a right - a switch, ie the left position or position rechts.Da at least I can be sure that they really on or off ist.Bei the old mouse is just a the switch is pressed for one and pushes again for aus.Da is ever the one that never happens from war.Also for me a real improvement.
