Buttons: The UGREEN 90545 wireless mouse uses a USB receiver rather than Bluetooth, with adjustable optical tracking and quiet-click claims. Its AA battery is not included, and the stated 18-month life depends on limited daily use.

## At a glance

- Six function buttons include forward and back navigation, a scroll wheel and a button for DPI or connection-mode switching, according to the listing.
- Five selectable DPI settings range from 800 to 4000 for adjusting pointer sensitivity.
- The manufacturer claims clicks are around 40 dB and describes the shape as ergonomic and portable.

## Pros

- A range of five DPI settings supports slower everyday pointer movement or higher sensitivity when desired.
- Six-button layout adds thumb navigation buttons beyond the standard left and right clicks.

## Cons

## Before you buy

- The 18-month battery claim is stated for one hour of use per day with a 3000mAh battery, so actual life depends on usage and battery capacity. The product information is inconsistent about weight, listing 72 Grams in specifications and 95 grams in a feature description. It also describes a 5-button mouse in one feature field but specifies 6 function buttons elsewhere, and gives different platform lists. Confirm the details relevant to your setup before buying.

## In the box

- Mouse (Included)
- USB receiver (Included): Stored beneath the mouse in the battery compartment, according to the product information.

## A good fit for

- People who want a receiver-based wireless mouse for a laptop or desktop and do not need Bluetooth.
- Quiet-work settings where lower-noise clicks are useful, subject to the manufacturer's noise claim.
- Users who want thumb navigation buttons and adjustable pointer sensitivity.

## Less suited to

- Anyone who needs Bluetooth or wants to connect without a USB receiver.
- Buyers who need an AA battery supplied in the box.
- Left-handed users, as the listed hand orientation is right.

## Customer feedback

Customer feedback reports appreciation for the quiet clicks, comfortable shape and straightforward setup. Battery life and responsiveness are mixed, while durability concerns are also reported. These experiences matter if the mouse will see daily use. The claimed 18-month battery life is conditional, and a favourable setup experience does not establish consistent responsiveness or longevity.
- Positive themes: Customers describe the mouse as quiet, comfortable and easy to set up.
- Positive themes: Some customers report good quality and value for money.
- Negative themes: Durability concerns include reports of units breaking quickly.
- Mixed feedback: Customers differ on battery life, with reports ranging from long-lasting to short-lived.
- Mixed feedback: Responsiveness is mixed, with some customers reporting lag.
