## Long description

The Contour Design UniMouse Left-Handed Wired is an ergonomic vertical mouse shaped for left-handed users. Its adjustable hinge and thumb support let you set the angle and hold that reduce wrist pronation and tension during prolonged computer use. Wired USB‑C connection and optical tracking up to 4000 DPI provide stable power and precise pointer control for office tasks, design work and extended sessions at the desk.
Advantages
The UniMouse combines a vertical form factor with a patented hinge and a five-way adjustable thumb support, offering both posture benefits and personalised fit. Multiple dedicated buttons and adjustable pointer speed deliver precise control without sacrificing comfort. The wired USB‑C power keeps the connection stable and latency low for reliable everyday performance.
Suitable for
Left-handed office workers who use a mouse for long periods
Graphic designers and CAD users who need precise cursor movement
Users seeking an ergonomic solution to reduce wrist and forearm strain
When it may not be suitable
The vertical shape and adjustable thumb support are designed for users prioritising ergonomics; those who prefer a traditional low-profile mouse or require a compact travel mouse may find this model bulky. Wired USB‑C connection requires a free USB‑C port and may be less convenient for users who need a wireless setup.
