Easy to snap
on October 5, 2026
Posted by: KikiD
[This review was collected as part of a promotion.] This was so much fun. This created bonding time for me and my kids. My son is autistic, and he even helped. This took less than 8 hours, not too heavy but it required two adults to lift off the floor.

Such a cute and fun build

[This review was collected as part of a promotion.] What a cute and fun Lego set! It took me about 3 hours to build with my daughter and it’s so much fun. The roller coaster track works surprisingly smooth. There are tons of tiny pieces that aren’t super fun to have around when baby sister is near but overall it’s so fun

Interactive Lego set
on September 5, 2026

[This review was collected as part of a promotion.] It was a two day process but the mermaid roller coaster ride was finally complete! The instructions were clear and straightforward, making the process very smooth. The roller coaster is sturdy and very interactive. This was the most complex and rewarding Lego set my daughter has completed!

Fun toy and fun to put together
on September 1, 2026

[This review was collected as part of a promotion.] I have had so much fun making this mermaid roller coaster with my daughter. She is only 4, so she’s a bit young, it she can still help me find pieces and put some together with guidance. Most importantly she has loved playing with the completed project. The roller coaster aspect does come apart sometimes, so that’s definitely something g to watch out for. It is also a bit large once built, so we’re still figuring out where we’ll keep it (especially since we also have a baby at home). Overall, I would highly recommend this toy. I think it has been great for getting my daughter into more mathematical-type play, although she is a bit young for it. She also found the potty detail hilarious!

Very Detailed Set
on August 30, 2026
Posted by: AnthonyD
[This review was collected as part of a promotion.] The Lego Roller Coaster Ride is a very detailed set that gave me some comfort while putting it together. The set has over eight hundred different pieces so it was quite a job. I love all the beautiful colors and watching it all come together was beautiful.

So fun! Exciting! Nostalgic! Super interactive!

[This review was collected as part of a promotion.] This is will take days to finish with my little one but what a fun core memory it already is! Such a nostalgia activity too! Very happy that theres more girl options since I was a kid. So many fun features and moving parts that my kiddo is already playing with as we are building. Very interactive and itll be a fun toy once finished (vs. a display piece). Such a great value and the size is worth it!

[This review was collected as part of a promotion.] I received this complimentary for my review. The design of this Lego set is awesome! My kids put it together in the vending over about a week. It has a moving roller coaster. It seems to be as durable as any other Lego set. The packaging is average for like products. Overall this is an awesome set and worth having!
