UGREEN appears once on this site, in ergonomic mice, with its 65042 vertical mouse.
The widest DPI range. Four levels — 1000, 1600, 2000 and 4000 — where the Anker and CSL stop at 1600 and the Logitech Lift gives no figure. On a large or high-resolution screen, the higher setting moves the cursor further for the same hand movement.
The broadest system list. It connects by 2.4 GHz or Bluetooth 5.4 to Windows, macOS, iOS, iPadOS, Android, ChromeOS and Linux, with a Mac mode that maps the side buttons to switching applications. The Logitech Lift lists five of those systems.
The shape and the clicks. UGREEN states a 57° grip angle — the same as the Lift — and quiet clicks aimed at shared offices and libraries. A low-power mode stretches battery life to about 12 months; batteries are not included.
What it leaves out. Which hands it suits: no dimensions, no weight and no size guidance, where the Anker gives 115 × 58 × 87 mm and 90 g and the Lift says right hands, small to medium. No warranty is stated either.
The price. About $22 on Amazon.com when we checked, against about $70 for the Logitech Lift — the only other mouse here with a US price.
