  1. Q1 202633/1004.0★3 reviews

    Mixed reviews: one user praises value, but two 0-star ratings (one verified, one incentivized) focus on pricing and promotion without clear criticism.

    • Pricing and value: one highlights low price, another calls it a deal, but stars don't match.
    • Promotional review: an incentivized review notes specs but no performance feedback.
    • Low star ratings: two 0-star reviews imply dissatisfaction not elaborated in text.
    • Product features: specs appreciated by one reviewer, but actual use not described.
  2. Q4 202567/1003 reviews

    Two reviews praise the vivid colors, ease of setup, and gaming performance. One review reports an unavoidable auto-brightness issue, dampening an otherwise great experience.

    • Vivid and vibrant colors, true blacks, excellent for gaming and video editing.
    • Easy assembly with only three pieces, good height and tilt adjustability.
    • Auto brightness cannot be disabled in OSD, causes annoying brightness shifts.
    • Glossy screen praised for clarity, but auto brightness flaw noted.

Based on 7 dated customer reviews, grouped by calendar quarter. Period analysis is in English.
