Was given to me as a gift in 1995 for mid to upper back/shoulder relief from computer typing/deadline stress. Phenomenal results. After that job ended in 2000, the massager set idle until my wife did a 60 mile walk in 3 days a year or so later. While massaging her aching thighs, got a little too high and she went into orbit. That's all I'll say about that. ;)
