Its obvious by them even admitting its not an official product , also obvious by the fact that they deliver by EMS which is from China thereby meaning if its a branded product its likely to be fake. You could get in trouble from customs if you order multiple quantities.

Ye, I just had a look at their faq haha, I gathered that at those prices they were going to be fake.
