not a fan of the Lego series 4-7

product of very good quality. no problem the above.
but I do not like the series 4-7 in the size of Legos (unlike duplo) but with large components already assembled (and tamperproof)
From 5 years old, my kids love lego normal and manage to climb them the same. younger, the duplo were very adequate Casa Anna-Paula I recommend this series ...
