Jimmy is right, at the £250 price point these would cost under 100 quid to make, this is not a lot for all the features.
I spoke to a guy who had purchased one on YouTube comments, he said it's very poorly built and the deck is very plasticy and stopped working after 6 weeks. Bluetooth is good and connects well but is not very powerful so doesn't get loud.
I have asked about a stockists near me so I can demo one.
