Battery life was widely praised, especially with RGB off; reviewers with RGB on reported shorter but still usable runtimes ranging from days to around a week.
Pros: latency, durability
Cons: legend visibility, rapid trigger support
Battery life was one of the clearest strengths, with many reviewers reporting days, a week, or longer between charges and generally validating the 50-hour RGB claim.
Pros: backlight brightness, actuation consistency
Cons: sound dampening, stabilizer quality
Battery life had limited evidence from the Mini Wireless review, where RGB-on runtime was criticized as poor.
Pros: per-key lighting control, key responsiveness
Cons: ease of switch replacement, battery life
