This is a basic mouse, not at all sophisticated. But it does its job. The wheel is serrated. We feel (the must) the "tic" in handling the mouse. The sound (noise) of the "tic" is relatively discreet, a "fleece tic" I would say, (other mice are more "noise" but this is of course a subjective interpretation based on personal habits). One note, however: "clicks" left and right are not sensitive enough. The same slight hardness clicks sometimes requires repeating the maneuver (the click or double click, for example = index finger less strong than the middle finger, in my case) it is boring. But it seems troubleshoots and enduring.
