You just want to smash it against the wall while remembering the entire mating vocabulary. Therefore, "+" does not overlap "-" in any way. Take a look at Logitech Got pros: If you have a MacBook, don't get this mouse. "+" mouse: - ergonomics - fits comfortably in a woman's hand, for a man it will be too small. - build quality - tight, expensive, cross. Got cons: If you have a mac, be prepared for the fact that: - the program with the settings of the mouse buttons will be installed, but will not work, because it is not supported - connecting to your laptop-computer will become "2022 roulette" - you will never know if it will connect at all / at what time it will connect (+ you still have to hold down the buttons on the mouse to get the "reset mouse settings" mode (something like that) )
