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.

Good quality!
I bought this item for my son for his birthday. He absolutely love it! Age range is 7 and was able to follow the instructions to put it together all by himself. It was complicated enough to keep him interested, but not so complicated that he couldn’t build it. It is good quality and the carts run seamlessly on the tracks.
