Check this before buying a gaming mouse
The material is not insignificant: A gaming mouse should lie comfortably in the hand for a long time and allow a good grip. Inferior surfaces quickly cause sweaty hands and let the fingers slip off when the click is hectic. But here, too, it depends on the personal preference of the gamer. Some want heavily rubberized mice with a lot of grip, others prefer the opposite and need a smooth surface for their way of playing. It is therefore worthwhile to try mice over a longer period of time.
Left-handers are not at a disadvantage: there is an abundance of ergonomic mice that are supposed to relieve the wrist with a thumb rest and a slightly curved shape. Left-handers, however, usually have to limit themselves to symmetrical mice, which in the worst case also have two buttons for thumbs on the wrong side. It is worth taking a closer look at the equipment here.
DPI and IPS: The DPI (dots per inch) indicates how much movement data a mouse can register per inch (1 inch = 2.54 cm). The higher this value, the less players have to move the mouse to navigate the screen. The IPS value indicates how quickly a mouse can be moved without losing information.
