It is a well-known fact (not so well-known that I can cite sources though...) that having relatively frequent, satisfying sex is beneficial to your health. If I recall correctly having at least several orgasms a week reduces your risk of heart attack (This is why teenage boys rarely have heart attacks. Their most frequent partner can be relied upon for at least that many...).

That said, if this device improves peoples' sex lives, than it should be called a "health" device. With, I suspect, the blessing of most people here. Of course, if it doesn't work, that's another story.
