Re: plug in earth products shouldn't be used in america or the uk?

I'm not really concerned with my own grounding system, I'm more concerned with whether or not the author is correct in saying plug in earthing systems should not be promoted in america and the UK because the frequency of stray voltage.

The only three people I know who have tried plug-in grounding devices, myself included, have had stray voltage leaking into them from their devices. So I'm leaning towards thinking he's correct.

I'm really concerned that this miraculous movement could be de-railed by improper application.
The number of negative reviews for plug-in earthing products tells me that the alleged stray voltage issue might be the cause of this. pretty disturbing that people could be missing out on this life changing phenomena.
