So far so good
Negative ion necklace - interesting idea and figured I'd try it.  So far it seems to make a difference.  Maybe not a huge difference yet, but I have noticed that I am more awake/alert.  See, I'm in my 60s and I often will feel tired and if I am sitting, it's very easy for me to close my eyes and fall asleep just that fast.  With this necklace, it seems to help me resist falling asleep like that.  Maybe there are other benefits, but that's the one I have noticed.
