UGREEN's vertical ergonomic mouse pairs a 57° vertical angle and up to 4000 DPI optical sensor with 2.4GHz wireless (and reported Bluetooth) connectivity, plus silent clicks and long AAA battery life — making it a solid ergonomic office mouse for productivity. Some reviews note inconsistent connectivity descriptions (2.4GHz-only vs dual-mode), occasional tracking lag on very textured surfaces, and a learning curve for pointer precision; overall good for budget ergonomic use, mediocre for precision gaming.
Good for office or creative users seeking an affordable ergonomic vertical mouse; avoid if you need guaranteed Bluetooth-only operation or high-precision gaming.
