Wah piang, they got shop and you say that they cannot be
trusted, and it's coming from an individual, in this case a
competitor. It's like the road side ice cream man selling ice cream
but claims that the 7 eleven ice cream is not hygenic. Anyway,
think your price really too high, maybe $350 still reasonable... If
got shop, they can go back to the shop in case anything is faulty
and change a new one for example if there is a scratch. New one
doesn't mean it's completely working without any defects.
