• Ergonomic comfort design, relaxed hand and arm: The comfortable, sculpted ergonomic shape of this mouse naturally fits your hand
• Smooth thumb control: Track precisely with great cursor control on any surface and easy thumb-operated trackball. Adjust the cursor speed with Logitech Options software
• Perfect for tight workspaces: Because the trackball doesn’t move, it’s perfect for tight workspaces and busy desks and fits in seamlessly alongside your computer and keyboard
• Two ways to connect and multi-OS: Connect simply with Bluetooth or the USB receiver and never worry about drop-offs or lag up to a 10m (33 ft) range
• Mouse design includes sculpted post consumer recycled plastic: The M575 uses 50 percent for the graphite/black and 21 percent for the off-white; also uses FSC-certified paper for responsible packaging
• Up to 24 months of use from a single AA battery with the USB receiver. You may even forget your Logitech wireless trackball uses batteries at all
