I bought to go with my laptop, this mouse. Who does not want to work permanently on the touchpad of the laptop, which was to buy these inexpensive, yet coming from the Logitech brand manufacturers Cordless Mouse necessarily. Very good is also that the receiver can be housed in a small depression in the battery compartment and hence never gets lost. A bit annoying but at this price you should not expect too much, are already clearly audible clicks. If, for example, sitting in the university and often have to click during a lecture, the other, or it may already be Prof., be disturbed. So my feeling, as I perceive the click sound. How it is actually a few rows perceived earlier, I can not judge.
