  • Meant to be played with :)
Bought this on sale. Will worth the price! Very sturdy and a lot of fun to put together with my 7 year old. He played with it for several days before it ended on the shelf to be admired by everyone. Directions were easy to follow.

  • Lego never disappoints
Once again, my Grandson and I spent quality time assembling the Lego City Robot World Roller Coaster. As with all Lego products, the instructions are clear, the bags are numbered and the tool that is included, makes it easy to separate pieces wrongly placed. It is age appropriate as listed on the box and his younger sister really enjoyed playing with him as the roller coaster really works! They love that the little figure's heads swivel to change expression. As usual, the Lego detail, quality and enjoyment is amazing. ... show more
