Vertical wireless optical mouse Perixx PERIMICE 719L — left-handed, clickless silent design, black

Perixx PERIMICE 719L is a vertical wireless optical mouse designed specifically for left-handed users who need a neutral hand position during prolonged computer use. The black ergonomic housing places the hand in a handshake-like posture to reduce forearm pronation and wrist strain. A silent, clickless button mechanism provides quieter operation while optical tracking ensures reliable cursor control for office tasks, web browsing and long sessions at the PC.

Advantages

The vertical shape reduces wrist twisting and promotes a more natural forearm alignment compared with conventional horizontal mice. The clickless silent design minimizes clicking noise, making it suitable for shared workspaces or quiet environments. Wireless operation removes cable drag and increases desk freedom, while the optical sensor delivers stable tracking on most non-reflective surfaces. The compact vertical housing in black offers a discreet, professional appearance.

Suitable for

• Left-handed users seeking ergonomic alternatives to standard mice
• Office work: document editing, spreadsheets, email and web browsing
• Environments where low noise is important, such as libraries or meeting rooms
• Users with mild wrist discomfort who want reduced forearm pronation

Key specifications

• Form factor: vertical ergonomic design for left-handed use
• Connection: wireless (USB receiver)
• Sensor type: optical tracking suitable for everyday desktop surfaces
• Buttons: clickless silent mechanism
• Color: black

How to use

Connect the wireless USB receiver to an available USB port on your computer and allow the operating system to recognise the device. Place your hand on the mouse in a handshake position so the thumb rests on the inner side and fingers align with the primary controls. Use the optical sensor on a compatible surface; if tracking is inconsistent, place a mouse pad or non-reflective mat underneath. The clickless buttons operate with a low-noise mechanism—apply normal clicking pressure to register input.

Usage recommendations

For best ergonomic effect, alternate short breaks and hand stretches during long sessions and ensure the mouse is positioned at elbow height to maintain a neutral forearm. Use a flat, non-glossy surface to optimise optical tracking and check that the USB receiver is not obstructed by metal objects or dense cabling.
