Minimize movement and maximize comfort with the Logitech ERGO M575S wireless trackball mouse. Thumb control lets you move the cursor without moving your arm, while the sculpted ergonomic design fully supports your hand and keeps your forearm in a more natural position. This wireless ergonomic mouse has been developed by Logi Ergo Lab experts, user-tested and certified by ergonomists to give you 25% less muscle strain in your forearm (1). The smooth and responsive thumb control can be used anywhere – and since it doesn’t need to be moved, the ERGO M575S is perfect for tight setups and busy desks. Connect your ergonomic wireless mouse in no time via Bluetooth or the included Logi Bolt Receiver, and enjoy hours of comfort with up to 18 months of battery life (3). The plastic parts in the ERGO M575S Bluetooth trackball mouse are made with certified post-consumer recycled plastic — 52% for Graphite/Black and 21% for Off-White, giving a second life to end-of-life plastic from old consumer electronics and helping reduce our carbon footprint (4).
