Bin for years actually customer when "market leader" in terms of mice, but did because of pain in the wrist - really just for fun - like times so try a vertical mouse. I'm very pleasantly surprised. My mouse arm It's much better and compromising on ease of use I have so far not had to do. The mouse works under Windoze as well as Linux precise, the mouse wheel has a pleasant resistance and Button 4 + 5 are also easily accessible with the thumb. I would have for the course now not really expected. Although the mice probably weigh a few grams more for my taste, so far it has not yet proved to be a problem. Processing of the device is quite okay.
