Our Verdict
LAMZU THORN
Razer DeathAdder V4 Pro
The Razer DeathAdder V4 Pro and the LAMZU THORN are both lightweight wireless gaming mice with right-handed ergo shapes. The Razer is a little larger and best suited for bigger hands, while the LAMZU's slightly slimmer and shorter body works well for both palm and claw grips. Performance is excellent on both, but Razer includes an 8k-capable dongle in the box, whereas you need to buy one separately for the LAMZU. Razer also equips smoother-gliding feet and an optical scroll encoder that should improve scroll wheel durability compared to LAMZU's standard mechanical encoder. In software, Razer offers extra software tools like Dynamic Sensitivity and Sensor Rotation, which the LAMZU lacks.
