BEST ADVICE ALWAYS BUY FROM AMAZON(.com|.es|.co.uk|.de or wherever they are). You always can send it back easily and I suppose Amazon will receive the best quality batch, whenever possible. I suppose Amazon does not like many returns and will make demands towards sellers and suppliers. So, whenever possible, and large amounts of money are at stake, do not deal directly with China.
O, for the record, I am not a shareholder nor an employee of Amazon … cheers to Jeff Bezos
