How to choose a USB flash drive? Looking for advice from a professional expert?

It’s too complicated, we should do something practical! Just buy the Kingston one, and I’ll teach you how to distinguish between original and parallel imports. The original ones are all A-core. After you get the USB flash drive, you can use your hands. The fonts on the polished sides are all engraved with a concave feel (parallel imports will lose some color and have no feel when touched). In addition, if you hold the metal piece and bend it hard, the original ones will not show any signs (while parallel imports Obviously metal and plastic will separate) so be careful when buying a USB flash drive! Be careful not to be deceived
