This is the best gaming mouse, and it consists of a 6400dpi optical sensor that allows accurate tracking to as low as 1mm above the surface where the mouse is placed. The low-sense gamers benefit from this mouse since they can set to cut-off whenever the mouse is lifted.
Its right-handed ergonomic design has been maintained from the old model, but the side grips have been improved with rubber to enhance better control of the mouse. Rubber side grips give both low-sense and high-sense gamers to control the mouse more conveniently.
The gamers enjoy the high sensitive buttons and durable micro-switches. Players also enjoy gaming experience with the razer synapse with online cloud support. Every detail can be saved in the online cloud support after lifting the mouse while gaming.
