Great value.
I haven't tested it out for long but,  if it generates the negative ins it claims to its a great deal.  The last negative ion generator I purchased cost 7 times the cost of this one.<br />The item is bigger than I expected. I thought I could wear it around but,  it's a cheap plastic case. They could do so much better on the case design but,  for the price it's  good.
