The Matias Wireless USB-C Pro Mouse is made from high-quality PBT, a significantly superior material compared to conventional ABS plastic. It features an aluminum scroll wheel and a top button, a magnetically interchangeable top cover that can adapt to different hand sizes, as well as a comfortable, ergonomic shape. It has a rechargeable battery with an incredible lifespan of up to 3 years before it needs to be recharged. It is equipped with our patented USB-C Nano Receiver, the world's smallest wireless receiver for USB-C. Simply plug the receiver into your computer, and your mouse will work immediately. The AES-128-bit encryption for wireless transmission between the mouse and receiver ensures that the mouse is suitable for high-security environments in businesses or government agencies. Overall, the mouse has four buttons and scroll wheel functionality: - left button (traditional left click) made of PBT plastic - right button (traditional right click) made of PBT plastic - press down on the aluminum scroll wheel to activate the middle button - rotate the textured aluminum scroll wheel to scroll through screens - press the top aluminum button to get the "Browser Back" function on a PC, or any mouse function you desire on a Mac through the Mac OS mouse settings. All of these functions are possible without the need to install any software drivers. The mouse is plug and play. The absence of software drivers is also preferred in high-security environments. The OMRON switches inside the mouse are rated for up to 50 million activations, providing smooth activation with clear tactile feedback and a quiet but audible click.
