Counterfeiting, illegal and dangerous
Possession of counterfeit goods, like selling, is a criminal offence. Sellers and holders of counterfeit goods can be punished for this.
Moreover, the manufacture of copies is not subject to any control, and therefore does not meet any standards to ensure product conformity. And counterfeit sites do not consistently guarantee buyer protection and secure payment processing.
As a result, these products are potentially dangerous to your health and safety.
