This light weight gizmo is fantastic for seeing up in high cabinets, closet shelves, under furniture, behind large appliences, etc.  I have bad knees and my mother has a bad back.  It makes it hard to bend or climb even short ladders.  This gizmo saves us wasted efforts by showing us if something got pushed back on a shelf or fell behind the washing machine.  It is also great to see if my shoes (or cat for that matter) are under the bed.  So many uses.
