Short term it doesn't seem to have any negative effect except for a cleaner house which leads to a lower risk of disease and infection :)
Long term, nobody knows. Probably not good. Probably not half as bad as having bisphenol-A leak from your water bottle, lead leaking from brass tubing in your house, and going through X-ray machines at the airport and all the modern health risks around you, since the shocks are only in the millisecond and millijoule range.
If you're worrying about it, it would be a wise idea to stay away from this kind of product...
That is worrisome.
