Otherwise the product is smaller than I thought but seems to be quality, plastics and buttons are well adjusted ... just to have a rest FR adapter to use it and test the sound: - (
EDIT: After buying a UK-EN adapter because I did not have to return the enclosure to receive the same charger UK ... I have tested this compound, and the result is really not bad, the sound is good quality and powerful enough to use it on my terrace in the summer, the Bluetooth connection is very fast, good quality and seamless. In summary, good speaker especially for the price but a shame that the charger is in UK format.
Also I tried to contact the manufacturer through their website but I never got an answer ...
