It's a great concept but it isn't totally spill-proof and the food items get caught between the parts that spin.
If you ever catch yourself contemplating this item in the impulse aisle... DON'T DO IT. It's not worth even "trying" to see how it works. It's a good concept, but not for kids under 3. I poured a small handful of cheerios in the bowl and handed it to my 1 year old and her older sister (3). Within moments they had the entire bowl scattered on the floor. It's easy for ONE cheerio to get stuck between the bowl and the outer casing to where the bowl won't gyrate anymore.
I did not like this at all, complete waste of money
my bf bought this for his nephew and it does not work...the cereal still spilled and it was useless
My daughter proved it can still spill =).
