Tests failed to determine the manufacturer of the controller and flash memory. A normal flash drive from a good manufacturer at an affordable price. Different pros: Delivery on time. Normal manufacturer, large file write speed stabilizes at around 12.5 MB/s after a few minutes. A little, but the price is low. The case is neat, it's good that the cap can be attached to the back during operation - there is less chance of losing it. Different cons: Came formatted in FAT32 standard. The warranty period is not clear, as, indeed, with all purchases on this site. There are no warranty obligations in the description of the goods, there are also words about them in the accompanying documentation.
