UGREEN MU001 90531 Bluetooth & 2.4GHz Wireless Mouse
A slim symmetrical wireless mouse with two selectable connections: Bluetooth 5.0 for one paired host and 2.4GHz through the included USB-A nano receiver for a second host. One connection is active at a time. It is a pointer and navigation device rather than a medically corrective product; comfort depends on hand size, grip, desk height and individual preference.
Product overview
Overview
UGREEN MU001 is designed for portable everyday pointing with a low-profile, approximately 54g body excluding the battery. Its symmetrical shell is usable in either hand, although it does not add dedicated left-side or right-side navigation buttons.
A mode selector changes between the stored USB-A receiver connection and one Bluetooth 5.0 pairing. Switching changes the active host and may take a moment; it does not broadcast pointer actions to both computers at once. The receiver should be stored in the underside recess when not in use.
The optical sensor provides four hardware steps: 1000, 1600, 2000 and 4000 DPI; the exact listing states the selection is remembered separately by mode. DPI changes pointer movement per unit of physical travel; it is not a screen-resolution upgrade. Tracking quality still depends on the surface, operating-system settings and application behavior. The primary clicks and wheel are designed for low noise—artwork references a controlled test value up to 40dB—but room acoustics and handling change what is heard.

Know the exact controls and roles
Controls, connection modes and button map
The physical controls and stored wireless receiver determine how this exact model connects. The underside mode control chooses Bluetooth or receiver operation; only one host receives input at a time.
- Bluetooth 5.0 channel: pairs with one supported Bluetooth host.
- 2.4GHz channel: uses the included factory-paired USB-A nano receiver.
- Mode selector: changes the active connection; it does not create a second Bluetooth slot.
- DPI button: cycles 1000, 1600, 2000 and 4000 DPI.
- Primary controls: left click, right click and clickable scroll wheel in a symmetrical body.
- Battery and storage bay: accepts one AA cell and secures the receiver for travel.
Where it makes sense
Use scenarios
Choose the mouse by hand fit, connection method and control requirements—not by DPI alone.
- Switching between a Bluetooth tablet or laptop and a receiver-connected desktop, one at a time.
- Quiet shared work areas where lower click noise is preferred without needing side navigation buttons.
- Travel with a thin symmetrical mouse and stored receiver, provided the host supports Bluetooth or USB-A.
- Everyday browsing, spreadsheets, documents and presentations where an adjustable pointer and physical scroll wheel are useful.
- Shared or mobile workstations when the chosen connection mode is supported and the receiver can be stored safely during travel.
- Casual creative or game use where standard mouse controls are sufficient; this model is not presented as a programmable competitive-gaming controller.
A dependable first connection
Setup and usability guidance
Start with a clean, level work surface and the operating system’s normal mouse settings. Pair or connect only through the modes actually built into this model.
- Open the underside cover, install one fresh AA battery with correct polarity and choose the intended mode.
- For 2.4GHz, remove the stored receiver and connect it to a USB-A data port; the mouse is factory paired to that receiver.
- For Bluetooth, select Bluetooth mode, enter the documented pairing state and choose the UGREEN mouse in the host Bluetooth settings.
- If replacing an old pairing, remove the stale mouse entry from the host before pairing again.
- Move the mouse on an opaque surface and test left, right, scroll and wheel click.
- Cycle 1000, 1600, 2000 and 4000 DPI, then adjust system pointer speed for the display scale.
- Use the mode control to change hosts; allow the selected connection to wake and reconnect before clicking.
Match the whole chain
Compatible devices and systems
Basic pointing usually works through standard system mouse support, while navigation buttons, gestures and device switching can vary by operating system and application.
- Windows, macOS, Linux and ChromeOS hosts with standard Bluetooth mouse support or a USB-A data port.
- Bluetooth-capable laptops and tablets that accept a standard Bluetooth HID mouse.
- Desktop computers through the included USB-A receiver.
- USB-C-only hosts through Bluetooth or a separate data-capable USB-C-to-USB-A adapter for the receiver.
- Symmetrical use for left or right hand, subject to personal hand size and grip preference.
- No dedicated side buttons; basic pointer controls are the most portable across systems.
Capabilities
What this product does
- Stores one Bluetooth pairing and one 2.4GHz receiver connection for two selectable hosts.
- Uses a symmetrical low-profile body that does not force a right-thumb control layout.
- Remembers the selected DPI independently for the two modes according to the exact listing.
- Provides selectable DPI levels so the user can change pointer travel without installing special configuration software.
- Enters a power-saving state after inactivity and wakes through normal interaction as described for the exact model.
- Supports ordinary pointer, click and scroll functions on a compatible host.
Clear boundaries
What this product does not do
- It does not operate both connected computers simultaneously.
- It does not provide two Bluetooth channels; the second connection is the proprietary USB-A receiver.
- It does not include forward/back thumb buttons or a rechargeable battery.
- It does not change the display resolution, network speed or application performance when DPI is changed.
- It does not guarantee tracking on every transparent, mirrored, highly glossy or uneven surface. Use a suitable opaque mouse surface.
- It does not provide user-programmable macros or onboard gaming profiles unless separately documented; the listed controls have their normal fixed roles.
Good practice
What to do
- Use the exact battery type and polarity shown inside the compartment, and remove an exhausted or leaking cell promptly.
- Store the USB receiver in its built-in recess when travelling, where the exact model includes receiver storage.
- Set the DPI to a comfortable value, then fine-tune pointer speed and accessibility settings in the operating system.
- Keep the optical sensor window and desk surface free of dust, hair and moisture.
- Use a relaxed grip and neutral desk arrangement; take breaks if any input device causes discomfort.
- Switch the mouse off for long storage and remove disposable batteries if it will remain unused for an extended period.
Avoid these mistakes
What not to do
- Do not force the USB receiver into a USB-C-only port; use a separate data-capable adapter or hub.
- Do not mix battery chemistries, old and new cells or reversed polarity, and do not attempt to recharge disposable batteries.
- Do not describe low-noise switches as completely silent; impact sound varies with desk, room and click force.
- Do not open the mouse, stare into the sensor aperture, wet-clean internal parts or use abrasive solvent on the shell.
- Do not expect side-button behavior to be identical in every macOS, Linux, Android, browser or application environment.
- Do not rely on the advertised open-space range through metal cabinets, dense Wi-Fi traffic or multiple walls.
Important safety and performance notes
Warnings and limitations
Wireless range, battery runtime and click noise are measured under selected conditions and vary in normal use.
- The listed wireless range is up to about 10m in suitable open conditions; host placement and radio congestion can reduce it.
- The listed estimates are up to about 12 months in Bluetooth mode and 18 months in 2.4GHz mode under selected conditions; real runtime varies strongly.
- Small batteries and the nano receiver are ingestion hazards. Keep them away from young children and pets.
- A vertical or contoured shape can feel unfamiliar. Increase use gradually and stop if pain, numbness or strain develops; no ergonomic shape is a treatment.
- Wireless devices can experience interference near USB 3.x hubs, 2.4GHz routers and metal surfaces. Reposition the receiver or host when the pointer skips.
- Side-button commands depend on host and application support; save work before relying on them for navigation in unfamiliar software.
Keep it working and solve common issues
Care, troubleshooting and buying checklist
First determine whether the problem is power, connection mode, sensor surface or software.
- 2.4GHz mode fails: confirm the correct stored receiver is in a working USB-A port and select receiver mode.
- Bluetooth fails: remove a stale pairing, confirm Bluetooth mode and pair again close to the host.
- Wrong computer moves: use the mode selector and wait for the intended channel to reconnect; one channel is active at a time.
- Pointer jumps: clean the sensor, use an opaque mouse pad, reduce reflective light and move the receiver away from congested USB or wireless equipment.
- Buttons act differently: test in a standard browser or file manager and check operating-system mouse settings; side actions are not universal.
- Short range: remove obstructions, bring the receiver closer with a suitable extension or hub and avoid placing it directly beside a noisy USB 3.x device.
- Slow or fast pointer: cycle the hardware DPI and then adjust system pointer speed; acceleration settings can make the same DPI feel different.
- Buying check: verify hand orientation and size, connection modes, host port type, required batteries and whether navigation buttons are supported in your main applications.
