For the price, what can you say... I use it as a Bootable usb and it hasn't shown any issue so far.

Unfriendly behavior.
In one port, it is not recognized. In disk management, it appears as a removable device (no media) -> problem with the controller.

In another port, it is seen normally.

For its price, it is considered good. It is recognized immediately. File transfer is around 13 MB/s for both recording and reading. The metal cover loosens a bit with use. We will see about durability.

I used it to upload songs. I tried it more than twice, thinking that the first time I had made a mistake. The playback was like all the songs were damaged, with crackling sound as if I was listening to a vinyl record... I didn't have any problems with another USB stick. Also, on the fourth day, the plastic broke and the metal tip of the USB was no longer stable.

It cannot be made bootable with any method. I don't have this problem with any other flash drive.

It's my mistake for buying 4 without trying it first
