First look:
1. All the cases are made of polycarbonated materials, not nylon material case,
so the temperature endurence is much higher;
2. All the cores are made of imported highest quality silicon iron sheet,
so the core's magnetic performance is much higher;
3. All the parameters are double cross-checked, so the testing results is much ensured!
