The ergonomic mouse Permice-513 L for left-handed users prevents wrist strain through its vertical, upward-facing hand position, which is commonly found in traditional mice. The vertical ergonomic design ensures that prolonged use of the mouse does not lead to pain or even tendonitis. The mouse can be used preventively to avoid discomfort. If there are already issues or strains such as RSI or tennis elbow, this mouse is particularly recommended, as it allows the hand to maintain a gentle, straight posture. With its thoughtful design, the mouse is ideally suited for both women's and men's hands in sizes S-M. The six buttons can be operated comfortably and effortlessly. The mouse does not require a driver and works via plug & play. It is recommended for use with Windows XP, Vista, 7, 8, 10, or later versions. The vertical design promotes a healthy, ergonomic hand position, recommended for RSI syndrome and for prevention.
