For under £2.50 I wasn't expecting much.
I LOVE THIS BOWL!
It works brilliantly, my 12 month old toddler has walked across the room without spilling a single cube of cheese on the floor, even when followed by hopeful cats!
The centre is designed to keep the snacks upright, and it responds very rapidly to movement.
We have managed to get things to tip out, by jolting it up and down without changing the angle of rotation, but that is to be expected, and goes against the movements the bowl is designed to compensate for.
Very technically minded small children will work out that if they jam their finger in the centre, it will prevent the gyroscope from working allowing the other hand to be used to tip it!
It is great for day to day use, comes apart for cleaning and contains a lid as well.
