This Mobile Holder We owe an evening hospital visit! The upper rod pulled away alone and fell along with our 7 week old son Mobile upside down! Only the slight shaking the cradle (by the kicking of the baby and "Schuckeln" the parents) has apparently been enough to get the rod out of the holder. Incredible! The rod is only inserted, there is no possibility of the locking! Added to put at the end of the rod a relatively heavy wooden blocks with sharp edges (why not round?). If this bar from a good meter height into the cradle, it can cause serious injury !!! Such a thing should not be sold! Our son was lucky and escaped unhurt, but this bracket moves immediately into the trash!
