carbon integrated handles (not all in one)

[Nickk2000]

has anyone bought carbon handlebars from aliexpress? the s works aerofly copies specifically. i have the ones that have the kocevlo branding on it and i can break them if i try hard enough horizontally, but to be honest, when will they feel horizontal stress and not vertical? anyone have experience with the specialized branded ones?

The specialized looks similar to the broken bar here, which is commonly sold on ali:
