■ The catch — co-equal billing, always
It weighs 150 g and it is palm-grip only. That mass forces a high-DPI, low-movement style — wide flick shots are genuinely harder, and competitive FPS players should keep a flat mouse. It has also drifted back to ~$114 against its $119.99 list, so the Keychron M5 now undercuts it by $44 for the same 30,000-DPI class.
Dealbreaker? Runner-up №1 is lighter, gentler and $44 cheaper ↓

The two-week wall
RTINGS, Wirecutter and CNN all warn of the same thing: expect a 1-2 week adjustment, polarized comfort reactions, and reduced precision on fine work because your hand sits further off the desk. Most people with mouse-related RSI report improvement within 2-4 weeks — but only if the body fits their hand.
Hand-size roulette
Hand size decides fit more than any spec, and a mismatched body undoes the entire ergonomic benefit. Measure wrist crease to middle fingertip first: under 17 cm is small, 17-19 cm medium, over 19 cm large. The Lift and DeLUX suit small-to-medium hands; the MX Vertical, Evoluent VM4 and Razer suit medium-to-large.
Glass desks are out
No vertical mouse tested works on a glass surface — every reviewer notes it, and there is no exception at any price. On a glass-topped desk you need a mousepad, or a different form factor entirely.
