1. First, check whether there is a trademark or brand name printed on the packaging box. There is a small font printed on the upper right corner or lower right corner. This kind of packaging means "registered". Only products with approved quality are eligible to use this kind of packaging. There will be no such mark on the packaging of counterfeit products; 2. Identification through the place of production and manufacturer. Other methods: The country or production region is often clearly marked on the back cover of electrical appliances. Through this, you can determine whether the product is manufactured by a local company or its overseas branch. If the back cover of the appliance is not clearly marked, you can confirm the place of production by looking at the printing location of the instructions. In addition, genuine home appliances produced by regular manufacturers can be easily found on the official website, but copycat products cannot. Through this, the authenticity can be quickly judged.
