You should check both temperature and lifetime rating of the capactors.

There are many capacitors on the market these days with 5000h or
even 2000h rated life.

That is 7 or 3 months respectively.

And yes, it should be criminal to manufacture and sell those.

Never attribute to malice what can adequately be explained by incompetence.
