ProtoArc EM11 NL Wireless Ergonomic Mouse, Bluetooth Rechargeable Vertical Mouse, 3 Multi-Device Connectivity - Black

The ProtoArc EM11 NL is a wireless vertical ergonomic mouse designed to reduce wrist strain and promote a more natural hand position during use. It connects to devices via Bluetooth 5.0 or the included 2.4GHz USB-A receiver, allowing users to connect up to three different devices simultaneously. The mouse features a built-in 500mAh rechargeable Li-Ion battery that is charged using a Type-C cable (provided for charging only). It offers three adjustable DPI levels (1000/1600/2400) for precise optical tracking, and includes forward and back buttons for easier web navigation (note: these buttons are not compatible with Mac OS systems). The left and right mouse buttons feature quiet clicking to minimize noise, while the middle scroll wheel and back/forward buttons are not silent. The ergonomic vertical design helps keep the wrist straight, potentially reducing discomfort and the risk of repetitive strain injuries compared to a standard mouse. This model is specifically designed for small to medium hands (under 7.5 inches / 19.05 cm) and is compatible with Windows 8, Windows 10 or higher, Mac OS X 10.12 or higher, and Android 4.3 or higher. Users may experience a learning curve of 1-2 weeks when transitioning to a vertical mouse.
