1. Identification
Famous brand products have manufacturer's marks on plastic shrapnel;
2. Transparency
Good products are crystal clear, but now counterfeit products are also very transparent;
3. Plasticity
When pressing with wire clamp, the crystal head with poor plasticity will break;
4. Elasticity of shrapnel
A high-quality crystal head can hear a clanking sound when it moves the shrapnel with its finger. If it moves the shrapnel forward to 90 degrees, the shrapnel will not break, and it will return to its original state and its elasticity will not change! A clear "click" sound can be heard when the finished crystal head is inserted into the hub equipment or network card;
Recently, a metal fragment crystal head has also emerged, which can be disassembled separately, solving the problem that plastic fragments are easy to break or lose elasticity
