This is a great toy. I purchased it for our 2 year old a few weeks ago(as his older brother had got a Playmobil castle for xmas and he showed a great deal of interest in it!) and he has enjoyed playing with it ever since.
It is small enough to chuck into the car for holidays and big enough to retain interest. I would recommedn purchasing the castle accessories pack (basically 2 more knights and horses, jester, queen and king) as my only critisism was the amount of figures to go with the castle.
That said, it is great fun and seems to have withstood everything a rather active 2 year old can throw at it!
