AI score breakdown
scored as defaultIts biggest strength is a category-leading feature set: a flagship MARKSMAN S sensor (33K DPI, 8,000Hz wired and wireless), tri-mode connectivity, 170-hour battery, and the first-ever dedicated Stream Deck launch button that no competitor offers. Its biggest weakness is physical execution for gaming, where reviewers consistently flag the heavy 89g body, hollow-feeling clicks, and a slippery coating that undermine its otherwise excellent tracking.
The overall score is the weighted average of these criteria — not a separate judgement. AI-generated scores are not hands-on test results. Percentages show each criterion's weight for this product type.
