Please contact customer service at the destination location to arrange another delivery and pay the corresponding price difference. (Free shipping is available only in the Chinese mainland)
·Regarding speed
All data stored in this store may affect the testing results due to differences in computer configuration and file size attributes.
Therefore, the actual speeds used vary.
·Regarding capacity
The actual usable capacity of the storage product is approximately 90% of what is indicated! This is due to the different capacity calculation methods used by computers and storage products (computers use 1G = 1024M, while storage products use 1G = 1000M). Additionally, some space is reserved before production for storing certain programs. All storage products follow the same pattern: 8G ≈ 7.4G, 16G ≈ 14.5G, 32G ≈ 28.8G, and 64G ≈ 58G.
·USB drive has no response when connected to the computer
Under normal circumstances, the drivers will be installed automatically. If it cannot be recognized, please turn off the computer’s firewall and antivirus software first before trying again.
If it still cannot be resolved, please contact the online customer service. Professional support will guide you to ensure your device functions properly.
·USB flash drive compatibility
1. Please ensure the USB drive is properly connected to the device.
2. Please confirm whether the device used supports a USB drive of this capacity and the corresponding file system (exFAT/NTFS).
3. Please confirm whether the files on your USB drive are supported by the device
4. The main control solutions used by different devices in the market vary, which may lead to compatibility issues.
· Unable to copy large files above 4G
To ensure compatibility with the system, the default format for products upon shipment is FTA3x2 (the default disk format used by Microsoft). A single file should not exceed 4GB. If you need to store files larger than 4GB, please reset the USB drive format: 1. Connect the USB drive to the computer. 2. Right-click on the USB drive partition and select “Format”. 3. Choose NTFS or exFAT as the file system format. 4. Click “Start” to complete the process.
·The device does not respond or takes a long time to recognize.
This situation may occur due to the USB flash drive not being properly connected or insufficient voltage at the computer's USB port. Please try using another USB port (desktop computers can use the USB port behind the case). If changing several USB ports or using another computer still fails to recognize it, then the USB flash drive may be damaged and requires repair.
·Expansion of USB flash drive recognition:
Expanding a USB drive involves using relevant software to make a very small capacity USB drive appear to have a much larger size on a computer (for example, 2G displayed as 8G). However, the extra memory cannot be used normally, and files stored in it cannot be opened, resulting in data loss.

Several notes regarding this USB drive:
1. Regarding the quality of the USB drive
All of our USB drives are obtained through legitimate channels, with chips rated above A+ level. They are definitely not counterfeit or fake products, nor are they expandable. We welcome your supervision. Additionally, we only produce high-quality items and never make counterfeit goods; please be aware of this. Regarding the capacity of the USB drives, we follow industry standards—for example, an 8G drive actually has approximately 7.45G of storage, rather than the 7.9G or 8G capacities found in counterfeit products.
2. Regarding the price of the USB drive
99% of our products come from direct suppliers, and we also offer direct pricing. Some customers still find the prices high—this is quite normal. There must be a reasonable standard for determining prices. If we compare our prices with those of counterfeit products, our prices are definitely much higher. Of course, we never produce counterfeit goods; different products and brands have no comparability. If we focus solely on price wars, it is impossible for us to make a profit! Our USB drives have a unified price across the entire network, and low-priced shipments are prohibited.
