UGREEN Portable Wireless Mouse — Gray (MU001)

The UGREEN Portable Wireless Mouse is a compact, ambidextrous cordless mouse designed for everyday computing across laptops, desktops, and Chromebooks. It connects via a 2.4 GHz USB nano-receiver — no drivers, no pairing sequence — and is ready to use within seconds of plugging in the receiver. The gray colourway suits neutral desk setups and pairs equally well with consumer laptops and professional workstations.

Design and Comfort

The MU001 uses a symmetrical, gently contoured shell that works equally well for right-handed and left-handed users. This ambidextrous form factor is relatively uncommon at this price point, where many competing mice restrict left-handed users to an awkward grip or require a dedicated left-hand variant. The low-profile shape keeps the wrist at a relaxed angle during standard desk use. Teflon glide pads on the underside allow the mouse to move smoothly across most desk surfaces — fabric mats, wood, and melamine finishes included — without the resistance that cheaper plastic feet tend to create over time.

The button layout is simple and deliberate: left click, right click, and a scroll wheel that also functions as a third click button. The DPI adjustment button sits on the underside near the sensor, which keeps the top surface uncluttered and prevents accidental sensitivity changes mid-task. This 3-button layout will suit most general computing workflows. However, users who rely on browser forward/back side buttons for document or web navigation should note that the MU001 does not include side buttons — the UGREEN FUN+ MU102 is the more appropriate option for that use case.

Silent Click Mechanism and Sensor

The MU001’s click buttons use low-noise micro-contact switches rated at no more than 40 dB, which reduces click noise by approximately 90% relative to standard mouse switches. This noise floor is low enough to be inaudible in most shared environments at normal seating distances. The optical sensor delivers accurate tracking across four selectable DPI levels and performs reliably on 2K, 4K, and 8K resolution screens where cursor speed and precision matter more than on standard 1080p displays. Line-by-line scroll wheel behaviour gives deliberate, controlled page navigation rather than free-spinning momentum, which reduces overshoot when reading documents or working through data.

Battery and Power Management

The MU001 runs on a single AA alkaline battery, not included in the box. A smart power-saving chip combined with a 30-minute auto-sleep timer extends estimated battery life to approximately 18 months under typical use conditions. This compares favourably with rechargeable models such as the UGREEN FUN+ MU102, which requires a USB-C charge every few weeks. The AA-based approach suits users who prefer infrequent, fast battery swaps over managing a charging cable. When the mouse does eventually need a new battery, any standard AA cell works — there is no proprietary format or USB-C dependency.

Use Cases

The MU001 is well suited to mobile workers and students who need a reliable, low-maintenance mouse for a laptop or Chromebook. Its compact dimensions fit easily into a laptop bag or backpack, and the receiver stores inside the mouse body so no components are lost in transit. Additionally, the plug-and-play setup means it works immediately on shared or borrowed machines without requiring driver permissions or account access.

For home office setups where desk space and cable management are priorities, the MU001 offers a simple, wire-free solution. The neutral gray finish blends into most workstation aesthetics, and the ambidextrous shape avoids the right-hand-only limitation of many similarly priced compact mice.

The MU001 is also a practical choice for library and co-working environments where click noise is a consideration. The ≤40 dB button noise level keeps the mouse audibly unobtrusive during prolonged sessions in quiet shared spaces.

However, users who regularly work across two or three devices, or who prefer Bluetooth connectivity to avoid occupying a USB port, should consider the UGREEN Multi-Mode Vertical Mouse MU008 or the UGREEN FUN+ MU102 instead. The MU001’s single 2.4 GHz connection means it is designed for one device at a time — which is precisely what most single-workstation users need.
