When I first tested this, it did not work properly. The chains got stuck and broke but after some fixing, it finally worked. It works better than ever now! Must buy!
I would recommend this to a friend!

Loop Coaster fail
on November 9, 2024
Posted by: Bobby126
Verified Purchase:No
Posting on behalf of my son: My name is Bobby, I’m 11 years old. The loop coaster was a complete disappointment. It took me a few days to build plus all the money I made over the summer. I was so excited to buy it, but now that it is built, there are a few malfunctions. Every single time the cars go down the vertical track, they fly right off—and that’s only when they can make it on the elevator. When the elevator goes down it can never push the red stopper, making it so the cars cannot get on the elevator; I have to manually push it down, and then when it gets to the top, the roller coaster cars cannot get off. This is a faulty design (I think this might be why I have never seen any official videos by Lego where it shows the cars actually move on the track). I have lots of Lego sets and this is the worst, and the second most expensive one I have (after Mos Eisley cantina).
No, I would not recommend this to a friend.

Lots of fun, some minor issues
on July 14, 2022
Posted by: ShadowShark31
First off, this set is such a beauty to behold. The color scheme and overall look of the ride is amazing. Some great building techniques, and amazing little details. Outside of waiting for a missing track piece to enjoy the complete ride, it is quite fun to play with.
The issues arise with the elevator. It is hard to adjust the elevator so the coaster leaves the elevator onto the track perfectly. There is a small gap which creates issues if everything is not properly calibrated. The chain has also broken a few times which is a little tedious to put back together.
Overall, an excellent set and addition to my collection of amusement park rides. As a roller coaster enthusiast, this is a must have and it did not disappoint.

Oh no! Looks like we’ve missed out on making the Loop Coaster as awesome as the other amusement park sets. Feedback from amazing builders like you helps us make our sets better. We’ll share your feedback with our design teams, so they know what our builders would like to see more of in our sets.

Doesn’t meet the Lego standard I’m used to.
on August 28, 2022
Posted by: Lambtronic
This is truly an amazing structure. The engineering involved with Lego always blows me away. The build was really fun and engaging. I finished more quickly than I’d expect, but no complaints on the build experience.
The coaster play aspect is really fun as well but this is where the issues arise. After less than a few weeks and not even using it that much the “chain” has already stretched out to the point where it doesn’t work anymore.
Further, I echo the other reviews in that you constantly need to make sure pieces don’t come loose or apart. We’re it not for the stability and product quality issues I’d give this a five star rating, even though it’s overpriced.

The build book is not cut correctly
on November 15, 2022
Posted by: StrictestCooperative
When you have a build book that was not cut correctly and you cannot see all pieces needed or where they go, it ruins the experience.
Also this set has so many missing pieces I haven’t finished it yet after purchasing when it first launched.
Not worth the price for a poor build experience.

Fun but lacks stability
on June 10, 2023
Posted by: EmpressLegendary019
I love this set, I really do. It is just fun. However, it does have a few issues. The main column on the build is not nearly stable enough. Any movement and the beam sways and can come apart. I built the Loop and had to move it. The coaster fell apart. On the plus side, I get to reassemble the main parts. Secondly, the tracks do tend to not line up perfectly at the beginning of the coaster so you really have to get the tracks adjusted well so it will work. Lastly, the base of this piece is flimsy. It needs to be more substantial due to the heaviness of the beam and it’s height. Even with these issues, I still would recommend this set to advanced builders.

Minifig Death Trap
on January 28, 2023
Posted by: MoldyBuffalo024
The design of the elevator is poor. The coaster gets stuck at the top leading to the platform to come crashing back to earth with the coaster and the poor figs on it. It slams to the bottom and the cars go everywhere. Also, I can also tell that motorizing it will be a pain. If the cars return and the chain return at about the same time it doesn’t allow time for the cars to load onto the elevator

Well, that's not a looping experience we want you to have. If you've not done so yet, please double-check your building steps and press all pieces together until you hear the 'click' sound. We're always happy to troubleshoot with you at LEGO.build/Service-BV.
