## Customer Reviews

### ⭐⭐ 







  
  
    Faulty unit - Temperamental Unit
  

*by H***5 on Reviewed in the United Kingdom on 20 March 2021*

The sound is great and easy to use. The only issues I have had was the first unit was always cutting out, returned and replaced with a new unit which works well but has developed a slight hum when the right speakers are connected, not to the left. Not recommended.
