Aliexpress cassettes? whats your opinions?

Many people didn't seem to recommend Aliexpress chains due to their poor mileage, potential to break, gear shifting issues etc

but what about Aliexpress cassettes? it's a static component with harder material unlike chains, so i think these will be not too bad of a choice? and it's 1/3 the price compared to Shimano cassettes.

Any experience or thoughts? Thank you
