This is a great set, with lots of details. My 4 year old girl build it without any problems and both my children love playing with it. Only downside is that many pieces are not attached or put on SNOT pieces to the side which means they easiliy get loose and lost. The set also contains many colorful bricks and is really fun to see. As for the instructions, I am absolutely no fan of the black pages. It makes it even harder to see the colours, especially in the evening. As an adult I really don't need black coloured pages to indicate that the set is intended for adults. I buy the sets I like based on the build and number of pieces.
