Palm grip comfort was mixed, with some reviewers comfortable using palm grip and others finding the narrow or long shape challenging.

Palm grip comfort was the weakest grip category, with most reviewers warning that palm users lose support or should steer clear.

Grip texture was mixed: many liked the grippy finish or tape, but some found the sides slippery, oily, or under-coated.

Grip texture was consistently praised for side traction and control without needing grip tape.

Premium feel was generally positive for specs and quality, but some reviewers found the look plain or unspectacular.

Premium feel was mixed, with textured sides and lightweight build earning praise while thin or canny plastic hurt the impression.

Switch feel was broadly praised for satisfying, tactile, responsive clicks, though some felt the switches were heavier than ideal.

Switch feel was usually satisfying and responsive, though one review called the primary click soft and undefined.

Battery life was consistently praised, with reviewers describing multi-day, fortnight, or even month-like usage and validating the long runtime claims.

Battery life was usually considered good to impressive, though some reviewers noted it trails certain competitors or drops in 2.4GHz/RGB use.

Cross-platform flexibility was praised for users switching among PCs, laptops, Macs, handhelds, tablets, or other devices.

Cross-platform compatibility had limited positive evidence tied to Bluetooth use with laptops and tablets.

Value was mixed-to-positive: many felt the performance justified the premium, while casual users and feature-heavy buyers saw the price as steep.

Value for money split reviewers: many praised the price-to-performance ratio, while others felt $80 was high for a basic or narrow-purpose mouse.

Customization was praised when reviewers focused on deep performance tuning and highly configurable buttons, but criticized when the physical button layout felt too sparse.

Button customization was a strength through iCUE remapping, but one reviewer ran into a frustrating side-button setup problem in Valorant.

Sensor performance was a standout strength, with reviewers repeatedly describing it as fast, accurate, responsive, or top-notch.

The Marksman sensor drew broad praise for flawless, responsive tracking, though one reviewer found very high DPI less ideal and another wanted better creative-work control.

MMO suitability was limited by the pared-back button set, making it less ideal for input-heavy games.

MMO gaming suitability was weak in the only opinionated evidence, which found the six-button layout too basic for MMOs.

RGB was modest but useful to some reviewers for DPI or battery indicators; others found it superfluous or noticed uneven lighting.

RGB was mixed: reviewers liked its minimal execution and sync options, but some called it boring, unnecessary, or hidden under the palm.

Glide smoothness was highly praised thanks to PTFE feet, low weight, and smooth movement across surfaces.

Glide smoothness was a consistent highlight, with many reviewers calling movement smooth, airy, effortless, or low-friction.

Fingertip comfort was mostly positive where reviewers felt the shape and light weight worked well for fingertip or hybrid fingertip use.

Fingertip grip comfort was broadly positive for small hands and compact control, but not universal across all hand sizes.

Claw grip comfort was split: some reviewers found the mouse useful or comfortable for claw grip, while others disliked the length or rear hump.

Claw grip comfort was generally positive, especially for small-to-medium hands, though one review found the rear grip lacking.

FPS suitability was a major strength, with reviewers repeatedly calling it excellent, esports-ready, and especially suited to fast shooters.

FPS gaming suitability was one of the strongest use cases, with reviewers repeatedly praising speed, flicking, precision, and shooter performance.

ROG ecosystem integration was praised because the Omni receiver could connect compatible ROG peripherals together.

Ecosystem integration was positive for users with Corsair gear, especially iCUE synchronization and multi-device setup.

Lift-off distance customization was useful but sometimes limited compared with rival software.

Lift height earned positive mention for helping rapid movements after setup and calibration.
