Its biggest strength is ergonomics — the integrated palm cushion and contoured shape earn strong comfort praise, backed by exceptional 24-month AA battery life. Its biggest weakness is latency, capped at 125Hz over Bluetooth with no bundled 2.4GHz receiver, making it unsuitable for anything beyond casual productivity use.

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.
