The UGREEN 65775 Wireless Multi-Mode Silent Mouse connects to any device via Bluetooth or 2.4G USB receiver — switching instantly between modes for Bluetooth-capable devices and non-Bluetooth computers from the same mouse. The silent click mechanism reduces click noise by 90% to below 40dB — virtually inaudible in libraries, shared offices and quiet home environments — while retaining the same satisfying click feel and responsive feedback. Four DPI levels (1000 / 1600 / 2000 / 4000) adjust sensitivity for any task and screen resolution, with the DPI setting remembered independently for each connection mode. The blue optical sensor tracks accurately on wood, fabric, plastic and most desk surfaces up to 10 metres from the connected device. Auto-sleep mode and an on/off switch extend battery life significantly between changes.
