Predictable feedback, mostly. Press the button and the same thing happens. It happens again the next time, and the time after that, which is what makes cause and effect satisfying rather than unsettling.
Toys of this kind also feed a special interest well. A child who is deep into flight, machines or coding will often stay with something that behaves consistently far longer than with something designed to surprise them.
The range covers hand-controlled flying ball spinners, a remote-control robot dog that walks and sings, gesture-sensing stunt cars, a domino-laying train, a 3D drawing pen and an LCD writing tablet. Quieter build-it options include a wooden dinosaur circuit board and a wind-powered car kit. Some of our customers carry the writing tablet to restaurants because it makes no sound and never runs out of paper.
Postage is free on any Australian order, and every one of them is tracked. GST sits inside the price on screen, with seven days of satisfaction cover once it arrives.
