“Best Mini LED TV for most people”: A What Hi-Fi? review from October 2025 awarded the 75C6KS (the UK version) an award, calling it an “absolute bargain.” The review praised its “excellent brightness and contrast” and comprehensive HDR support.
Mixed reviews on YouTube: Some YouTube reviews, like one from September 2025, have provided more critical perspectives, with one video questioning if the TV is truly worth the money, describing its positive and negative aspects.
General build quality: What Hi-Fi? noted that while the TV’s plastic build feels a bit basic when handled, it is not noticeable from a normal viewing distance. The review also commented on the remote control feeling lightweight.
