but unfortunately it will only occasionally function as it is supposed. My previous Logitech mouse had decided shortly after the guarantee to respond to a left click either with a simple click or by double-clicking (apparently a not entirely unknown phenomenon with Logitech). Unfortunately, I have decided to give Logitech again a chance to be a big mistake !! This mouse has now been supplying the character, left-click on either with a simple click (what's desired) to respond, or optionally only times no! And this really is unfortunately on the mouse, have tested it on multiple computers! In short, the next mouse does not come from the house of Logitech certainly!
