My husband and I purchased one of these bracelets each. We were both a little sceptical as to the advertised benefits. With both of us in our 70's we suffer a few aches and pains and thought lets give it a try.
All of a sudden we are sleeping better, headaches have disappeared and we wake up ready to go instead of feeling sluggish.
The bracelet is on all the time,very light weight so you forget you are wearing it.
We even bought one for a friend who couldn't believe the changes it effected in her life.
All I can say "is try it" and see what a difference it makes to your life.
