Personal experience/ opinion
I bought these energy armor bands at the mall for gifts and I got one for myself. The most marked difference I have noticed is in my mood and energy level. I don't know if it's the placebo effect or if it really works but I have noticed my mood being so much better, I'm not getting irritable as easily and I don't feel as tired when I get home from a long day at work. I haven't noticed any strength improvement but my balance is definitely better. It seems strange but if one band can make this difference...I will invest in more.
Reply: What is great and equally important is that it works for you!
Don't knock the placebo effect, it is a very powerful and beneficial process, whether it is at work here or not. If the bands provide a health benefit for you, so much the better and god luck with your investigations.
