I gaave this product a low review at first
The first time I tried it, it fell off the wall almost immediately.  It arrived with no instructions (which is why I am not giving it 5 stars).  I was going to return it, but decided to try one more time.  Applied more pressure when I attached it, and it has stayed on fine.  It is really helpful to my mom who is 84 and has a failed rotator cuff repair that prevents her from raising her arm above chest level.
