You've got two machines and a mouse, keyboard, maybe a scanner that keeps migrating between them. Cable swap. Reconnect. Repeat. This ATEN switch kills that routine. Plug your peripherals into the switch, connect both PCs, hit the button. Done. USB 3.2 Gen 1 gives you 5 Gbps transfer speeds, so a large project file moves in seconds, not minutes. No drivers to install. No software to update. Hot-plug any device in or out without powering anything down. Works on Windows, macOS, and Linux. Compact enough to disappear under your desk
