The UGREEN 90371 is a compact, 2.4 GHz optical mouse engineered for travel and quiet workspaces, offering precise and adaptable performance across various operating systems.
Silent Click Technology: Equipped with Mute Click buttons to drastically reduce operating noise (typically under $40\text{dB}$). This makes the mouse ideal for minimizing distractions in quiet environments, such as libraries or open-plan offices.
Adjustable DPI Sensitivity: Includes a dedicated switch to instantly cycle the optical sensor resolution through four adjustable levels, allowing users to optimize cursor speed and precision for different tasks.
Ergonomic and Portable Design: Features an ergonomic, contoured shape for comfortable, long-term use. Its mini size and secure internal storage compartment for the USB receiver make it highly suitable for travelers and mobile professionals.
Power Efficiency: Utilizes a smart power-saving chip that enables the mouse to enter a sleep mode after 30 minutes of inactivity, resulting in an estimated battery life of up to 18 months from a single AA battery.

Great quality
Good quality and arrived ahead of schedule. Very happy.
Brilliant Aussie deal
Been buying UGREEN gear for years and this is one of their better ones. The UGREEN 90371 quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.
No complaints at all
Exactly as described. Quick shipping. Would buy again.
Works perfectly out of the box
Was exactly what I needed for the price I paid. Arrived well packaged and was easy to set up straight away. Already recommended it to a friend who is also thinking of getting one.
Worth every cent
Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.
Does the job well
UGREEN quality is always reliable and this was no exception. Fast delivery too.
