This is a great introduction to Lego, which toddlers are totally enthralled by. Any of us who had this as children, take great pleasure in passing on the creativity to the next generation.
DON'T BUY IT FROM AMAZON!
It's cheaper at a certain supermarket's online store (under £10 = free P&P) - every little helps.
The rest of Amazon's Lego seems competitive from what I have observed.
But do buy it, especially if the youngster you are buying it for is not your own. Whoever's child you buy it for will instantly thank and respect you, for your insider knowledge ;-).
