Souris sans fil DEFENDER TOUCH MM-997 interface

The DEFENDER TOUCH MM-997 wireless mouse combines silent click technology with adjustable DPI settings and an ergonomic form in a compact black design. It provides three sensitivity levels (800, 1200, 1600 DPI) to accommodate precise pointer control for office tasks and casual gaming. The wireless connection removes cable clutter while the low-power design extends battery life for prolonged use between replacements.

Advantages

Silent click technology reduces audible feedback for quieter operation in shared environments. Switchable DPI allows quick adaptation between detailed pointer movements and faster cursor travel. Its ergonomic shape promotes a comfortable grip during extended sessions, and the compact footprint makes it easy to carry with laptops or store on crowded desks.
