A friend raved about the waver board and how it helped her joints feel better. Thought it was worth a try and have not been disappointed. As a retiree who has become more sedentary than I would like, the waver board instills in me a more active mindset just by stimulating my whole body with its motion.
I was skeptical at first but after hearing my wife confirm what others have said (that pains she was having fade away after using the device) I am a believer.
