### ⭐⭐⭐⭐⭐ Amazing
*by A***S on 1 December 2025*

Absolutely awesome product

### ⭐⭐⭐ Improvement in Dolby, Out-the-box performance has much to be desired
*by K***N on 2 January 2026*

I like the ability to use the colour sliders to pick the intensity and blend of each light but the colours are much more washed-out out-the-box compared to it's 1 port counterpart. The single port was much more vivid and punchy. It does take some tinkering to get it back to how I usually like it(by putting white in the negatives and increasing RGB). It is a lot more responsive and can handle VRR and ALLM and Dolby Vision/Atmos quite well as opposed to the single port. They do give you more LEDS per Metre which does make the lighting smoother and less gappy and segregated.
