Hey all!! I have a question for everyone. My wife and I have gone through like three wand massagers. They are not really broken, but there is a little screw that holds a metal splash plate down to the wand. That screw keeps coming loose everytime my wife uses the wand. Has anyone else had this problem with the wand? And if so how did you keep the screw from vibrating loose everytime you use the massager? Thanks for the help everyone!!!
