Good on a bad day
Knobbing your own back is always great therapy for us office dogs, since I am on a computer 12 hrs a day (work, home).  I am in pain everyday from these damn laptops, so medication and the back knobber is a good combo to help me cope with my pain.<br /><br />-2 star because of SAFETY:  I am a man, and I like working the deep tissue.  THIS THING WILL COME APART UNDER GREAT PRESSURE (pushing down on my shoulder blade).  The middle section splits apart (unlatches itself) and shoots across the room at great velocity, 10-15 foot range.
