One GORILLA WAND owner, an 80+YO ex-cowboy reported debilitating arthritis in his left-hand knuckles. He received a demonstration treatment at an equestrian event and after 24 hours saw some improvement. He bought his GORILLA WAND the next day. Two months after buying his WAND he reports “full use of his left hand” and that “it is as strong as his right hand now”.
