Key features

• Stop chasing a mouse around. Your trackball stays in one place and puts control under your thumb, so you don't have to move your arm to move your cursor. And its sculpted shape supports your hand for comfortable control all day long.
• You can go for up to 18 months without changing batteries and the convenient battery indicator helps to ensure that you'll never be caught off guard. Battery life may vary based on user and computing conditions.
• You get precise cursor control wherever you want to use your trackball. Hard tables, comfy sofas and lumpy beds are all no problem for the M570.
