In all respects a pleasant mouse. Almost inaudible clicks and a wheel - this is especially true when traveling, when the family is sleeping in a hotel, and something needs to be done at work. But I had to get used to it - at the moment of clicking, the mouse often slips away on the rug, as a result, you can miss or drag-n-drop. An unpleasant trifle is a backlash in the switch (on / off). When moving the mouse, it produces a "rattle" sound.
