Sam, thank you for reminding me that the author of that warning about other wands may be motivated to protect his own business of making these wands. I want to belive the pair I bought are as good as any. Glad to hear you're seeing improvements! Whenever I'm riding in the car or not using my hands, I hold the wands, or at least I try to remember to do this, up to two hours a day. Barefoot at sunset, my hands tingle immediately on holding the wands. Riding in the car, it takes a bit longer to feel the electric effect. Now heading out into the morning sun to sniff wild roses and connect with the earth. :)
