Title: Contour Butterfly 3-in-1 Massage pillow
Review: For using just to keep your heels off the bed, it's great. However, the battery container has to be pulled out of its glued in posistion in order to insert batteries (bad design) and the battery connections fall out and/or disconnect every time you move the pillow to a different position. (bad design)
