UGREEN MU001 90531 Bluetooth and 2.4 GHz Wireless Mouse

Overview

The UGREEN MU001 (90531) is a slim, quiet wireless mouse in Starry Black that connects either over Bluetooth 5.0 or through a 2.4 GHz USB-A receiver, so it can serve a laptop and a desktop, or a tablet and a PC, switching between them. It has a thin symmetrical shape for either hand, weighs about 54 g without its AA battery and has four speed settings.

Is it right for you?

• Suits anyone who moves between two devices: one paired over Bluetooth, one using the receiver, one at a time.
• Suits left or right-handed use; the thin body has no fixed thumb rest, and fit depends on hand size and grip.
• Suits tablets and laptops that accept a standard Bluetooth mouse, including USB-C-only computers.
• If you want forward and back thumb buttons or a rechargeable battery, choose another model.

Key features

• Two connections: one Bluetooth 5.0 pairing plus one 2.4 GHz receiver host, selected one at a time.
• Four pointer speeds of 1000, 1600, 2000 and 4000 dots per inch (DPI), remembered separately for each mode; no configuration software needed.
• Low-noise controls to cut office click noise (they are not completely silent).
• Light body of about 54 g without the battery.
• The USB-A nano receiver stores in the underside compartment.
• Range up to about 10 m in open conditions.
• Rated battery life of up to about 12 months in Bluetooth mode and 18 months in 2.4 GHz mode; it sleeps after inactivity and wakes with normal use.

What else you need

• One AA battery, which is not included.
• A device with standard Bluetooth mouse support or a USB-A data port, running Windows, macOS, Linux or ChromeOS. A USB-C-only computer connects by Bluetooth or needs a data-capable USB-C to USB-A adapter for the receiver.

Installation

Fit the AA battery, then either plug the receiver into a USB-A port or pair the mouse from the device’s Bluetooth settings. No software is needed.

Before you buy

• It controls one connected device at a time, not both at once.
• It has one Bluetooth channel; the second connection is the receiver, not a second Bluetooth pairing.
• No forward and back thumb buttons, and not rechargeable.
• Changing DPI does not change display resolution, network speed or application performance.
• Tracking is not guaranteed on transparent, mirrored, very glossy or uneven surfaces; use an opaque mouse surface.
• No programmable macros or onboard gaming profiles.
• Real battery runtime varies strongly with use.
• Interference near USB 3.x hubs, 2.4 GHz routers and metal surfaces can make the pointer skip; move the receiver or the host.
• The battery and nano receiver are small enough to swallow; keep them away from young children and pets.
• Stop using it if pain, numbness or strain develops; no mouse shape is a treatment.
