2pcs 2.4G Wireless Air Mouse Thumb-Controlled Handheld Trackball Mouse USB Port (Black)

Set of two 2.4G wireless handheld trackball mice designed for portable, off-table operation so you can control the pointer without resting the device on a surface — ideal for laptop users. The finger/thumb-operated trackball helps reduce strain on palm joints and muscles during long periods of use. Because it enables you to sit farther from the screen, it can lessen exposure to monitor radiation and reduce eye fatigue. Ergonomically shaped like a dolphin and fitted with left and right clickers, it suits both left- and right-handed users. Connects via USB port and functions as plug-and-play with no software or drivers required.
