    Great Build with Fun Easter Egg

    I love this set, but ironically not for the coaster itself. It’s overall a fun build in and of itself, but the mech suit was what sold me on it as I don’t typically collect coasters. BUT, the mech suit brought me back to my childhood as it’s a callback to a theme long-forgotten by many. Of course I’m referring to EXO-Force! I absolutely LOVED that theme as a kid, and the Stealth Hunter (7700) was my first of MANY EXO Force sets to collect! 💙 It’s wonderful to see LEGO paying homage to themes from our childhood!

    Excellent

    This was perfect for my son. And entertaining for both of us. He loved the skill level and loves roller-coaster's so this was a good one. He plays with it daily.

    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.

    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!!

    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!

    Family fun!!

    [This review was collected as part of a promotion.] My 10year old loves this! It is easy to assemble and fun for hours. It’s very durable and you can do many things with the pieces. There are small pieces so be careful with little kids. The whole family has had fun with this!

    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.

    Functional roller coaster

    [This review was collected as part of a promotion.] The fact that it was 986 pieces did not stop my children from putting this together they love the fact that I was a functional roller coaster and they are having so much fun with it it did take them about 4 hours to complete which kept them busy which I love that part and they also learned how to connect with each other share and build something.
