### ⭐⭐⭐⭐⭐ Compact & quality.
*by T***A on 6 November 2025*

More connection ports than the one I replaced it with. Smaller but better. Quality audio output without feedback & static noises like the previous one I replaced it with. Compact better remote control.

### ⭐⭐⭐⭐ Works fine - although the supplied hdmi lead looks a bit cheap
*by R***H on 17 March 2021*

The only niggle was that it's powered by usb. No power supply is provided so you need to use your own if you want to use it at the back of your tv.
