BEWARE!!!
The instructions for placing it in the door jam are terrible. Beware if you don’t have a lot of clearance between the jam and the wall, it cannot hook on. Then once you’ve found a door that it will fit, the minute you exert your body weight against it, it will fall off. This is a great idea to loosen that sore spot on your back or neck, but it doesn’t work at all. Also, BEWARE, it says free shipping but unlike almost all other Amazon buys, you pay the return shipping.  Update: it’s been 30 days since they received my return and still no refund.
