I tried clicking your link, but it came up as an error report?
One of the best things for you to do, is to ask the seller if they are genuine or not.
I have done this before, and the seller has told me that they are 'genuine replica's.'
If they lie, then when you recieve your product, and discover it is in fact a fake, you dispute on DHgate, and they seller gets a negative feedback, or banned from DHgate.
On top of this, you get your money back (minus shipping I think) from Dhgate, which has it in a holding account.
Hope this helps.
