Scroll 1000 rows in a second. The UGREEN M571 is the wireless mouse built for deep office work — analysts, developers, data professionals, researchers, and anyone who spends their day inside spreadsheets, long documents, codebases, and dashboards where a standard scroll wheel adds friction to every large vertical movement. The hyper-fast scroll wheel moves through 1000 rows of data per second in free-spinning mode — what takes 20 seconds of standard scrolling to reach takes two on the M571. That is the single most productivity-relevant feature for users who scroll heavily.
The hyper-fast scroll wheel is physically different from a standard ratcheted scroll wheel. Standard mouse wheels click through each notch as they scroll, providing tactile position feedback at the cost of scroll speed. The M571's free-spinning wheel mode disengages the ratchet and allows the wheel to spin freely — a single firm scroll gesture sends the wheel into continuous rotation that covers hundreds of document rows, webpage lengths, or spreadsheet lines in a single motion. The thumb-positioned side scroll wheel adds horizontal scrolling for wide spreadsheets and wide-view documents without requiring shift+scroll or horizontal trackpad swipes.
Bluetooth 5.4 and 2.4GHz dual-mode connects to three devices simultaneously — two Bluetooth devices and one 2.4G USB receiver device. Switch between all three with a dedicated button. This is the mouse for the professional who uses a Windows desktop at work, a MacBook at home, and an iPad for reading — the M571 remembers all three pairings and switches between them without re-pairing.
5000 DPI at five adjustable levels (1000/1600/2400/3200/5000) provides precise control across display sizes from standard 1080p to 4K and ultra-wide. Silent clicks reduce acoustic output for shared office environments. The 6-button layout — left, right, scroll, DPI button, back, forward — covers the full navigation range for browser and document workflows.
The 2×AA battery configuration delivers 240 days of typical use — approximately 8 months from one pair of AA batteries, with auto-sleep after 60 seconds of inactivity. For users who prefer not to worry about charging schedules and want months-long battery independence, the AA battery approach provides a guaranteed power reserve that rechargeable mice cannot match without access to a charger.
