China has a habit of CE marking rubbish that doesn't comply, as they are not part of the European Market they are not bothered, will not refund or take returns.... this is why if you plan to invest money make sure your not the fall guy and you get it from a reputable European or UK distributer.
I've seen machinery built in China come over with all the CE marks but are Electrical deathtraps and then refuse to accept returns - I open the eyes to one company who were acting as the UK distributer.
