I hope the story described in the shortcomings will not repeat itself and this was a single factory formatting glitch. Has pros: 1. Actual write speed (displayed in Win7 usb 3.0 while copying files to a flash drive) from 30 to 50 Mb/s depending on the file size. I usually showed about 45 mb / s. 2. There is a keychain hole. 3. The retractable mechanism works perfectly, nothing dangles, does not creak. 4. In the extended state, the connector itself does not move back in until you press the button. 5. Due to the matte rough plastic, the button and the body of the flash drive itself do not slip. Has cons: I inserted a new flash drive into USB 3.0, tried to copy a couple of movies, less than 4 GB in size. The flash drive from the package was already formatted as fat32. While copying the first movie, the flash drive gave a message that it already has such a file with a size of "0" kb. I clicked "replace", got an error that the file is corrupted or something like that. Despite the fact that from the computer this movie ran perfectly. In general, the film was copied from the second time. Further, when copying the second movie, he copied it from the first time, but when I tried to play it from a flash drive, I got a message that the file was damaged. In general, all this gayness seems to have been defeated by formatting, but again, I pressed full formatting under fat32, the default cluster size. Formatting has ended. I'm trying to go to the USB flash drive and it gives me "the device is not formatted, do you want to format it?". And so I pressed formatting again, but I already chose "fast". After that, I went normally to the USB flash drive and normally copied the archive with documents weighing 450mb, quickly and without glitches.
