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!

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

Fun family activity.
[This review was collected as part of a promotion.] My kids are enjoying working together building Robort World Rollercoater Park. 986 pieces. The Lego App Builder makes building the set so convenient with Lego party. We used a couple of tablets and worked in teams to build the 1st part - the robot and people. The kids are happily playing with those parts alone. The robot took an hour to complete minus the kids playing with the people and building their own stuff.

The kids love it!
[This review was collected as part of a promotion.] My kids (9 and 13) had an absolute blast building this! We're a huge Lego family, so they jumped right in! They split the bags up so it was even, and they both were able to do fun steps. Like everything Lego, quality is amazing and the book had easy to follow instructions. The mini figs are super cute and they love how the heads are reversible so they can change their expressions. The rollercoaster is a lot of fun, and they both have really enjoyed playing with it in different ways! As always, Lego did a great job!
