UGREEN 90545 Wireless Mouse, 4000 DPI, 6 Buttons

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.

Pros and cons

Pros

USB receiver setup avoids pairing steps and is described as plug and play.
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

Bluetooth is not supported, so the mouse relies on a USB receiver connection.
The AA battery needed for use is not included.

What to know before buying

Listing details to confirm

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.

Who is it for?

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 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.
