Specific details on latency and battery life are unknown, so users sensitive to input delay or battery endurance should consider this.

Buttons & Customization

It includes programmable buttons and adjustable DPI settings, enabling users to tailor responsiveness and controls to their workflow. Customization is enhanced through AI-powered software, which simplifies setting adjustments and macros. The extent of onboard memory for profiles is unknown.

Trade-offs

The vertical shape, while ergonomic, may not suit users seeking a lightweight or compact mouse for fast, precise movements. Unknown factors include battery life and latency, which could impact wireless performance. The software reliance on AI customization may not appeal to users preferring manual control or minimal software use.
