Just contrary, cheap products / poor engineering team use them on devices such as low end laptop chargers, usually on the DC power cord to pass EMC compliance tests. A good designed product fix them in the electronic circuits.

An underrated observation. For example, the worst USB cables in my experience aren't the ones with no ferrites, they're the ones with the ferrites.
