Gadget Speak reviews the HEXBUG.
Put to the kiddie test, our 11 and 13 year olds played with them for hours! I thought they might be the sort of thing you open, watch it do a trick or two, and then forget it. However, our kids rapidly turned on their imaginations and started making little maze warrens for them from upturned CD boxes. Having two of them was definately more fun than one. Only problem – we played with them until the batteries ran out on one!
