This ESD protection device is based on "Corona effect"

It is NOT ACCEPTABLE as an effective ESD protection system on a production
line for electronic equipment.
Can be used by people inspecting the production floor or people
transporting crates full of equipped PCB.
In no way it should be used by people handling PCBs populated with
semiconductor devices.

This was quite popular some years ago and we had to spend much time and
persuasion to get these completely banned from production floors. Even
"strap devices" can fail and are often not used the correct way, so just
think about these.

ESD is a major issue and is getting worse daily since semiconductor
technologies bring design rules in the range of 90 nm and shrinking all the
time. It does not take much to "blast" these things.
