Unlike so many other toys, this simple Montessori toy requires some great wrist rotation, therefore it is perfect for babies to learn to transfer an object from one hand to another. that the interlocking disks are not meant to be separated. When you tap it, it rolls forward and shakes, which will motivate babies to move.

I absolutely love this product. I have a 10 month old who is teething, a toddler with autism and a 7 year old with severe ADHD and I gave them each one of this toy. My toddler didn't care much for it, but my 10 month old and 7 year old love them and always have to have them with.

Interlocking Discs not very heavy, perfect for baby’s hands, improves hand-eye coordination, concentration, grasping and exploring skills.Minimalistic and great for parents who don't want their baby to chew on plastic all day.These were perfect!!

Grandbaby loves this toy. When he drops it and it tumbles away, he wiggles and jiggles to get it back. He likes to turn it around in his hands. Great for Montessori approach and hand dexterity.

This is a good toy for fine motor skills, eye hand coordination. My 5 month old baby can move it from one hand to the other. She seems to love playing with it.

Gave it 4 stars out of 5 only because the size is a little bit bigger than I thought, but the width is good for children to chew on. Overall the quality is good just on the wider size.

Good, solid product. Easy for baby to grab. So far he just puts everything in his mouth, but it’s withstanding all the slobber. This toy is good for passing objects from hand to hand.
