Propeller crash in the air

Hi all,

I'm doing the maiden flights of my new Y6 but I don't know why extrange reason propellers brake in the air.

I know that are cheap propellers with low quality:

But I didn't expect that after 5 minutes working the propeller can explode like this.

I already broken more than 5 propellers.

This is a little video when it's brake:

Can be the vibrations of the motor? Or something diferent?

Did you visually inspect all propellers for cracks or other defects before use? Did you check the propeller adapters for sharp protrusions that could be cutting the prop hub? Are you over tightening the prop adapters and crushing the prop hub? Are you using the correct shaft adapter? Are the propellers that break always on the same motor?
