Trabalhamos com Sound Vitality desde 2008 e estamos muito satisfeitos com o Infratonia Ciência Sonora. O Infratonia 9 [New Design:  CHI Palm] has helped Jack not only with his sleeping issues, but when he wakes up in the middle of the night with his sinuses completely plugged up, he reaches for the 9 and places it on his sinuses. He shortly returns to restful sleep, and when he wakes up, his sinus cavity is completely clear!
