Great play experience
I really like this set as it is full of life and the rollercoaster is fun. The only issue I had with it is the transparent part of the robot. That falls off easily. Otherwise, great.

Awesome set!
Item was in perfect condition and arrived within a few days. My son loved it! He had asked for it since before xmas but it was sold out at the lego store. Finally found it here for a reasonable price. Highly recommend!

Roller lego
[This review was collected as part of a promotion.] I just bought this set for a friend we worked on it. It was cool and interactive. It was not to hard to assemble for a 5 year old. Just a fun way for a kid to concentrate for a bit.

Lego Fun!
[This review was collected as part of a promotion.] My son absolutely loves Legos and he really enjoyed this project! The Legos always come in strong material to build the best! Very easy instructions to follow even it being a large set to put together! He loves building and taking pics and puts on his shelf as collection! This one really was great and helped in creativity and stemming his brain!!

Excellent set
An all around great set. It has a good number of fun minifigures, has a great color palette and I dig the little references to Bionicle and Exo-Force. My only complaint is that this set has a lot of stickers. They do a lot to give the set its overall feel, but I get paranoid about how they're going to age.

My 2nd grader loves this kit. He asked his big brother for a help a couple of times, but absolutely loves it.
