MUS-TRKF248

Strongly tilted ergonomic shape that reduces wrist twisting. Quiet design. The left and right buttons use switches that passed a 3-million-click durability test. *The wheel button is not silent. The "Forward" and "Back" buttons make web browsing comfortable. Compatible with [Digio2 Mouse Setting], which lets you customize the Wheel, Forward, and Back buttons (Windows and Mac only). Pointer speed can be switched in 3 steps. The receiver can be stored on the underside, preventing it from being lost while carrying. <Precautions for Use> The included battery is for operation testing only. Its remaining charge may have decreased during shipping. After confirming operation, replace it with a new battery before use. If the ball feels sluggish or the pointer responds slowly, try applying a small amount of hand cream thinly to the ball. This reduces friction and may improve movement. Please clean the bearings that support the ball regularly.
