I ordered the wand on Friday and received it today (Monday) so I started to play with it right away, my thumb and knee were in a little pain and truth be told in just a few min I no longer have any pain. So anyone reading this and if your not sure if it works that's okay you don't have to believe in it because it works anyway, this is not a mind over matter and it’s not magic it’s just the best darn thing you can offer your self or family. Thank you so much for a wonderful product this will be used in my office.
