These cars are fantastic. They are great quality and far more durable than any others we have come across. They do tend to get left behind at supermarkets, playgrounds etc, so I have bought several packs. They used to be £5, but I see they have now increased to £7. It's still less than £1 per car, so not too bad, especially for the quality. While they are supposed to be for 3 years +, my boys have played with them from as young as 12 months and never had a problem. I trust them because the last and last. And the types don't have rubber rings like other brands. Highly recommend.
