How well is that actually going to work? UVC sterilization usually takes much longer than 30 seconds.
Just because you don't see how it can be that fast doesn't mean you should immediately jump to false advertising. Think of it like cooking chicken to a safe temperature, you can do it sous vide at a lower temperature and still get safe chicken it'll just take 8 hours or you can throw it in an incinerator at a thousand degrees and have it sterilized in a few seconds.
Sterilized is more than just the amount of time it's also the amount of exposure, an extremely strong UV light needs significantly less time than a weaker one
It’s dose dependent not just time dependent. LED uv-c emitters can pump a huge dose onto a surface from a short distance such as this device does.
This recent study showed viral inactivation using such shorter time frames.
