Sandisk ULTRA 32GB - LED does not flash

Just bought a SANDISK ULTRA® USB 3.0 FLASH DRIVE 32GB https://ru.sandisk.com/home/usb-flash/ultra-usb.
The operation LED does not flash. On the video from other people in YouTube (https://www.youtube.com/watch?v=dPsoyuWvBW0),
I see how the work LED flashes blue or red. Does my flash drive work properly?

Does it stay blank when you write to it?

The flash drive works correctly both writing and reading, the testing program passes, errors = 0. But the indicator for some reason does not work. And I need official information from Sandisk - is there an indicator in this flash drive or not, should it work here to blink or is it a Chinese counterfeit? So that I can say in the store when I return the flash drive.

When you return it simply say it’s not working as you expected and you would like to try a new one.  Or a different one.

The answer came from the authorized representative Sandisk, which says that there are two versions of this USB flash drive: one - has a work LED indicator, the other - without an LED indicator of work.
I got - without an LED indicator of work.
Thank you all for your attention.
