What it does well.
Key features
Hand orientation. Ambidextrous / either hand.
Shape. Slim symmetrical.
Grip guidance. compact fingertip or relaxed claw grip; suitability depends on hand size.
Comfort boundary. Ergonomic describes the physical contour, not a medical treatment. Hand size, posture, desk height and grip preference determine comfort; take regular movement breaks.
Connection modes and device switching
Connection: 2.4GHz wireless through the included USB-A nano receiver.
Host handling: one receiver-based host connection. No Bluetooth and no multi-device switching.
Range: Up to 10m in suitable unobstructed conditions. Keep the receiver away from heavily shielded ports, crowded 2.4GHz equipment and large metal obstacles.
USB-C note: the supplied receiver is USB-A. A physical USB-C fit requires a compatible data-capable adapter or hub; a charging-only adapter will not work.
Controls and DPI: what each setting changes
Controls: Left click, right click, scroll/middle click; underside DPI selector and power switch. None.
1000 DPI. Measured pointer movement for precise tasks.
1600 DPI. Balanced everyday navigation; choose by feel and task.
2000 DPI. Balanced everyday navigation; choose by feel and task.
4000 DPI. Fast pointer travel across a large or high-resolution desktop.
DPI is pointer sensitivity. It does not prove polling rate, latency, gaming class, display sharpness or tracking on every surface.
Reduced-noise controls
What is quieter. The main clicking design is intended to reduce repetitive click noise in shared work, libraries, meetings and late-night use.
What remains audible. Scroll-wheel steps, mode and DPI switches, side buttons, desk contact and physical movement may still make sound.
No percentage promise.
User-friendly placement. Use a clean mouse pad and light clicking pressure; a rough desk can create more movement noise than the buttons.
Battery, sleep and power management
Power: 1 × AA battery, not included. This is a replaceable-battery mouse, not a rechargeable mouse.
Battery estimate: Up to 18 months under UGREEN usage conditions. Sleep: Automatic sleep helps reduce power use.
Battery care: insert with correct polarity; use one fresh, undamaged battery of the required type; do not mix chemistries; remove it for long storage; recycle depleted batteries through an appropriate collection route.
Setup and usability guidance
- Open the compartment: locate the receiver and battery bay without forcing the cover.
- Install power: insert 1 × aa battery, not included with the printed polarity.
- Select the connection: insert the supplied USB-A receiver into a compatible host or data-capable adapter.
- Switch on: use the physical power switch and wait for the host to recognise the pointer.
- Set sensitivity: press the DPI control and test each level on your normal screen.
- Check buttons: confirm scrolling and any side-button behaviour in the actual operating system and application.
Use scenarios
Office and home work. Navigate documents, spreadsheets, presentations, web pages and ordinary desktop applications.
Study and shared spaces. Reduced-noise clicks suit libraries, classrooms, meetings and rooms where repetitive clicking can distract.
Laptop travel. The cable-free design and nano receiver simplify portable setups; store the receiver securely and switch the mouse off before packing.
Multi-screen work. Higher DPI can move the pointer faster across a large desktop; choose a lower setting when fine placement matters.
Tablet use. A tablet must support USB host/OTG and a compatible data adapter for the USB-A receiver.
Casual games. Adjustable DPI may suit casual play, but no competitive polling rate, macro software or latency number is verified.
Compatible devices and systems
System guidance: Windows 7/8/8.1/10/11, macOS 10.5 or later, ChromeOS and Linux; compatible USB host required.
Windows PCs. Primary pointer, click and wheel functions should work after standard plug-and-play or Bluetooth pairing. Shortcut behaviour is application-dependent.
Mac computers. Primary functions are supported on compatible systems; side-button and mode-button behaviour can differ from Windows.
Chromebooks and Linux. Basic HID mouse functions are expected on compatible hosts; advanced remapping is not promised.
Phones and tablets. A listed mobile OS does not guarantee every app supports a pointer. USB receiver use also requires host/OTG support and a data adapter.
Optical tracking and surface guidance
The optical sensor is intended for common, clean, flat work surfaces such as a mouse pad, paper, finished wood and suitable fabric.
Use a mouse pad when the desk is transparent, mirrored, highly reflective, glossy, uneven or heavily patterned. Dust, hair, moisture and low battery can affect tracking.
No “works on every surface” promise is made. Clear glass and mirrors are specifically not guaranteed.
What this product does
- Provides standard optical pointer, click and scroll input to a compatible host.
- Connects by 2.4ghz wireless through the included usb-a nano receiver.
- Offers 4 DPI settings: 1000, 1600, 2000, 4000.
- Uses a reduced-noise control design for everyday productivity.
- Runs from 1 × aa battery, not included with automatic sleep helps reduce power use.
What this product does not do
- It is not rechargeable and has no charging port or built-in battery.
- It does not transfer files, add storage, improve display resolution or replace a Bluetooth adapter for other accessories.
- It does not guarantee medical relief, injury prevention or correct posture.
- It does not provide competitive-gaming polling rate, programmable macros or zero-latency performance.
- It does not guarantee tracking on glass, mirrors or every material.
What to do
Choose the correct SKU. Match the colour, shape, connection method and DPI list to SKU 90372; related UGREEN mice are not interchangeable.
Check hand fit. Confirm ambidextrous / either hand placement and the preferred grip before long sessions. Change posture and take movement breaks.
Protect the receiver. Use the storage position where verified, or a secure accessory pouch. A lost receiver may not be replaceable by a generic dongle.
Keep firmware expectations simple. Use operating-system pointer settings for ordinary adjustment. No model-specific programming software is promised.
What not to do
Do not force covers or ports. Align the battery cover and receiver correctly; never bend the receiver or jam it into USB-C.
Do not expose to hazards. Keep away from liquid, high heat, flames, direct impact, crushing and loose metal objects.
Do not use a damaged battery. Stop if a battery leaks, swells, overheats or has damaged wrapping. Avoid skin contact with leaked material.
Do not overstate the product. Quiet is not silent; ergonomic is not medical; high DPI is not a gaming-performance certificate.
Warnings and limitations
Cleaning: switch off, remove the receiver and battery, then wipe with a soft dry cloth. Use no solvent, spray, abrasive or dripping cloth; keep the optical opening dry.
Radio use: nearby 2.4GHz devices, USB 3.x electrical noise, metal barriers and crowded wireless environments can reduce range. Move the receiver or use a short extension/hub if appropriate.
Storage: switch off before travel, secure the receiver, remove the battery for extended storage and keep the product away from children and pets.
Stop use: discontinue use after liquid ingress, impact damage, persistent overheating, burning smell, cracked housing, exposed battery contacts or unstable USB connection.
