As the other reviewer says this brush is fantastic, ideal for my 5 year old, who loves the Cars film. He actually enjoys brushing his teeth now and the results are excellent.
However the brush heads are soft to protect the young ones teeth, which is good, but as a consequence they don't last that long and a cost of around £5 a head for something that is smaller than a regular toothbrush costing less than half that it is rather pricey. Add to that you can pick the up on the High Street or in Supermarkets for £10 at regular price and the Amazon marketplace price of £11+ doesn't look so good.
I know Oral-B will have to pay Disney Pixar a license for using the Cars theme but even so, come on guys, price them at a reasonable level or start offering larger packs at a better price point as you do with the white Adult versions!
