The Lenovo Go Wireless Vertical Mouse in Storm Grey is designed to reduce wrist strain by placing your hand in a natural handshake position with a 45-degree palm grip. This ergonomic shape makes it a helpful choice for right-handed users who spend long hours at a computer and want to avoid the discomfort of traditional flat mice. It connects via a 2.4 GHz wireless USB receiver, offering a clean workspace without cables. You can adjust the optical sensor's sensitivity between 800, 1600, and 2400 dpi to match your screen resolution or task precision. The device features six buttons in total, three of which are programmable, allowing you to customize shortcuts for your specific workflow. To ensure a secure hold, the plastic body is complemented by a cork-like side grip that feels natural against the skin. Weighing 96 g and measuring 62 x 104 x 63 mm, it remains compact while providing enough support for the hand. The mouse runs on a single AA battery and includes an on/off switch to preserve power when not in use, with switches rated for up to 3 million clicks for long-term reliability on Windows systems.
