Bought this for my 5yr old as older brother had Lego Advent calendar! What a waste of £20 only 11 tiny pieces of figures, the other doors opened were stickers or pieces of card with a picture of Ben 10! Never again Lego it is next year then!!!
My son was pleased just because it was Ben 10 and the excitement to the lead up to Christmas but if your looking for something that will be looked at after Xmas I wouldn't bother playmobil is much better
