1. Identification
Famous brand products have manufacturer's markings on plastic shrapnel;
2. Transparency
Good products are crystal clear, but nowadays counterfeit products are also very transparent;
3. Plasticity
When pressing with wire pliers, crystal heads with poor plasticity may experience fragmentation and other phenomena;
4. Fragment elasticity
A high-quality crystal head can hear a clanking sound when fingering the shrapnel. Move the shrapnel forward to 90 degrees, and the shrapnel will not break, but will return to its original state and its elasticity will not change! When inserting the prepared crystal head into the hub device or network card, a clear "click" sound can be heard;
Recently, a metal bullet crystal head has also emerged, which can be disassembled separately, solving the problem of plastic bullet easily breaking or losing elasticity
5. Packaging
The authentic packaging should be in colored boxes, and it is recommended to choose colored boxes when purchasing.
6. Copper strip color
The color of genuine crystal head copper sheets is dark yellow and thick, while the color of counterfeit copper sheets is light yellow. The metal contact sheets are relatively thin and thin, and there may be deviation and asymmetry in the internal copper sheets during wire pressing.
