Nice picture, but not for me
[This review was collected as part of a promotion.] The display quality was genuinely impressive, deep blacks, sharp detail, and rich colours, especially with 4K content. But I found the software slow and clunky, and the interface wasn’t as intuitive as I expected. For the price, I hoped for a smoother, more user-friendly experience. It didn’t feel like an upgrade, so I ended up returning it.

Super smart TV
[This review was collected as part of a promotion.] After 1 month of having this TV I am absolutely amazed about the picture quality and sound performance. It has good design and it is easy to use. The interface is great and you can always choose so much easier from home page. Also easy to connect it and to interact with. The fact that it is a 2025 TV makes it more attractive as it’s the most up to date TV interface you can find on the market plus it is an OLED AI. I can very impressed and I highly recommend it.
