UGREEN Multimode WRLS Mouse 2.4GHZ Bluetooth (Black) / 65773
The UGREEN M331 (item 65773) is a multi-mode wireless mouse that connects either by Bluetooth or through the included 2.4GHz USB receiver. It can be paired with two devices and switched between them with one press, and it offers four DPI levels up to 4000.
Two connection modes: Use the 2.4GHz USB receiver for a computer with a USB-A port, or Bluetooth for a laptop, tablet or phone without a free USB port. This lets one mouse work with almost any device you use.

Two devices, one press to switch: The mouse remembers two devices, for example a laptop on 2.4GHz and a tablet on Bluetooth. A short press of the button switches between them, so you do not need to pair again each time.
Four DPI levels: Hold the button to change the sensitivity between 1000, 1600, 2000 and 4000 DPI. Lower values give fine control, higher values move the cursor across large or high-resolution screens with less hand movement.

Clear indicator lights: A green light shows 2.4G mode and a blue light shows Bluetooth mode, so you always know which device the mouse is connected to. A low-battery warning light tells you when the battery is running low.
Power saving: The mouse enters light standby after a few seconds without use and deep sleep after 10 minutes. This helps the battery last longer when the mouse is left on the desk.
Who it's for / Works with
Windows 7/8/10/11, macOS 10.5 and later, Android 6.0 and later, and Chrome OS devices, through the 2.4GHz receiver or Bluetooth.
Good to know
- Bluetooth mode requires a device with Bluetooth; 2.4GHz mode requires a free USB-A port for the receiver.
