It has changed our lives, after a car accident we were both plagued with the after effects of the physical and emotional injuries. Having the Duospa has brought us closer, given us time to heal mentally and has also been the key part of physical healing. To know we can use it instead of popping pills to cope with the pain is so uplifting. And after two years of owning it we still use it twice daily. To be honest the Duospa is right up there with sliced bread and running water!
