Nikken has been around for quite a while and I think their
business practices are at least reputable.  Among other things,
they forbid their distributors to advertise on newsgroups and
will terminate a distributorship for violating that rule.  It's
a cut above many of the other MLM companies.

However, evidence showing that static magnetic fields have much
effect on your health is pretty skimpy so far.

If you believe that magnets can cure everything............
Legitimate-yes.
MLM, afraid so.
