My 4 year old daughter had seen this advertised and was desperate for this for Christmas, and so I bought it although I could tell it was overpriced and of limited potential. She loves it, but I think it is feeble in terms of only having 3 small areas for colour change, one of which (yellow on flesh) hardly shows up at all. More of the hair could change and there could be more colour change patches on her , e.g on her arms or clothing. She enjoys playing with it in the bath, and even her 8 year old brother secretly loves making the colour change. I am worried that if she brushes the hair too vigorously it will not last long - but its been fine so far. In a sane world it would cost under £10.
