What should I pay attention to when buying a USB flash drive?

Buy a Kingston USB flash drive with a five-year warranty. It is recommended that you don't buy USB flash drives on the Internet or on street stalls. Expand the USB flash drives on the Internet and on the street stalls into large-capacity USB flash drives and small-capacity USB flash drives. Don't believe how good the online merchants are, ensure the quality, and the website verification is genuine. Online profiteers use real packaging boxes or fake USB flash drives, which are verified to be true by Kingston official website, and problems often occur. You'd better go to the local trust store designated by Kingston to buy a USB flash drive. Trust store's USB flash drive is genuine, not fake. In order to buy safely, the dealer is required to issue a receipt and indicate that if the test result is false, it will be returned. Pay attention to the following points when buying a USB flash drive: whether the packaging box is clearly printed and whether the sealing of the USB flash drive is long or short. I'll teach you two methods to detect the authenticity of U disk: one is to use software: download a U disk authenticity detection tool from the Internet, and take Kingston 4Gu disk as an example to detect the actual capacity of U disk: real display: actual capacity: 390MB (normal).

Congratulations! Removable disks don't look like extended disks.

False display: 256MB, 5 12MB, 1G or 2G at most.

Attention! The test found problems!

This USB flash drive can expand 256MB, 5 12MB, 1G or 2g flash memory!

Beware of counterfeiting!

Next, download a USB flash drive \MP3 main chip detection tool. The chips for detecting the USB flash drive are as follows:

Device name: [I:] USB mass storage device (Kingston Datatraveler 2.0 USB device)

Product manufacturer: kingston

Product model: Is DataTraveler 2.0 Kingston's?

The second method is to log in to Kingston official website. The verification method is as follows: after you log in to Kingston official website, 1 uses SMS: click technical support-click product verification-click verification of digital storage products-flash memory and products in SMS query: edit the SMS "F+ product SN serial number and send it to 02 12 333 0345 to verify the authenticity. The second method, product warranty method: click the finished product warranty-enter the digital product warranty registration-click the old label for the old label, click the new label for the new label-fill in the product information (need to add an asterisk) in the digital storage product warranty registration interface, fill in your email address: (you apply for a QQ email address first, Sina and Yahoo email addresses are not recommended), and fill in the product serial number (SN). Fill in the country/region (fill in China) on the warranty card on the package. Leave the contents below blank, just click Send. If it is an old label, just click the old label with a hint. Kingston official website will send you an email telling you whether it is made in Kingston. If the detection result is different from that detected by the above two methods, it is false. There are too many fake 800 fake phone calls now, which leads many people to fall for it. The following are the assured stores designated by Kingston: provinces and cities.
