### ⭐⭐⭐⭐⭐ Excellent picture quality
*by M***N on 22 July 2026*

Really pleased with this TV. The picture is bright, sharp and colourful, and the smart features are easy to use. Straightforward to set up and excellent value for the quality.

### ⭐⭐⭐⭐⭐ Great quality TV. Easy to set up
*by A***R on 13 July 2026*

Great quality TV. Excellent quality picture clarity and sound. So easy to set up and working. First class and and a reasonable price point

### ⭐⭐⭐⭐⭐ Big upgrade, excellent picture, and finally no more HDMI headaches
*by G***O on 23 November 2025*

We’ve stuck with Samsung TVs for years — mainly for the quality and reliability — and this 65” QLED has been a fantastic upgrade for our family. We were replacing a well-loved but aging TV (over a decade old), and the difference is night and day. Setup was a breeze — we’re running this with a Sonos Beam, Sub, and two Play:1s for surround sound, and everything just worked straight away. With our old TV we always had minor issues with audio syncing or switching sources, but this time the setup was smooth and stayed stable. The picture is excellent — rich colours, crisp detail, and much brighter than our previous TV. Even standard-definition programmes look better thanks to the built-in AI upscaling. 4K and HDR content really pops, and the larger screen size has made a real difference for movie nights. We also have a Fire TV Cube, but honestly, it feels a bit redundant now. The built-in Samsung interface is snappy and includes all the main streaming apps we use (Netflix, Disney+, Prime, etc). Unless you need something really specific, the native smart system does the job well. We use it for a bit of everything — films, kids’ shows, the odd game console — and it handles all of it with no fuss. Pros: •Fantastic picture, especially for 4K and HDR content •Easy integration with our Sonos system •Built-in apps and Samsung smart hub are fast and full-featured •Reliable brand we trust (and it shows) Minor cons: •Not quite the top-tier gaming specs (no 120Hz or full HDMI 2.1), but still fine for casual use. It’s not been an issue for us at all. Overall, this has been a great buy. If you’re ready for a proper upgrade and want something that just works, this is a solid choice. No regrets!
