Firmware reliability received a positive mention for seamless firmware updates.

FPS suitability was one of the strongest areas, with repeated praise for competitive aiming, speed, and esports performance.

FPS gaming suitability was mixed: casual and general FPS play worked well, but pure competitive or solo FPS users may prefer lighter/faster mice.

Glide smoothness was consistently praised across stock PTFE feet and multiple surfaces.

Glide smoothness was broadly praised due to PTFE feet, though some reviewers felt weight or skate slipperiness held it back.

Grip texture was the most divided attribute, ranging from non-slip praise to strong complaints about slippery coating.

Handedness options were a core strength, with reviewers repeatedly praising true ambidextrous support and left-handed usefulness.

Left and right click quality was mostly positive, with praise for consistency and similar actuation between sides.

Main click quality was mostly praised for tactile feedback and responsiveness, though one reviewer found the feel cheap or off.

Lift-off distance was mixed: one reviewer liked the low setting, while another found low too low and high too high.
