9 - 24 months. This multi-activity toy is ideal for stimulating early cognitive and fine-motor skills. Everything baby touches makes something happen: a clicking dial to turn with mesmerizing graphics, moving bead maze for hand-eye coordination, turn the cube over to see the colored disk spiral down. Turn cube over again and spin the transparent "rainstick" tube to see the little balls tumble down through the sections. The unbreakable mirror provides excellent visual stimulation and encourages self-recognition. The sliding "abacus" disks help to develop fine motor control and introduce counting.
