Hopes were not met

This build is visually amazing and as an avid collector I was so excited to build this. Sadly, I was left disappointed and wish I had picked another set. The engineering is great in theory but after 2 hours of troubleshooting, I still can't get many parts of this set to function. Additionally, a lot of the crucial elements to this set are being held together by few pieces. I wish LEGO had put more supports in for more essential elements instead of abandoning flimsy technology to focus on decor. Overall, really upset and as an expert builder who saved up a while for this set, I wish I could have a refund. I'm so upset :(
No, I would not recommend this to a friend.

Feat of Engineering
on July 5, 2022

I don’t often find myself writing reviews for anything. But this set blew me away. From the elevator with operating counter weight, to the stop at the platform for new passengers to get on while the elevator was in the air. There are so many cool and impressive design techniques that just were awesome to put together. I also felt like there were a lot of new pieces I hadn’t seen before either which was cool, although I would have been ok skipping the step that made you put all the small chain links together. I would definitely recommend anyone who is on the fence about this set get it. It won’t disappoint and was one of my favorite builds in a very long time. This will definitely be a set I rebuild a few times simply because of how cool it was to see everything working together as I was building it. And the sheer size of the completed model is very impressive.
I would recommend this to a friend!

Loop coaster is so much fun and to me worth it!
on September 22, 2022

This is my first Lego build and review and I am hooked. Yes the instructions can be hard to understand, but if you have patience, you can build this 3700 piece coaster. One piece of advice is to ensure not to rush through it and TAKE your time. After I assembled everything it took another hour to figure out why the car would not run on the track smoothly. All the Lego’s must be tight!!
I also hooked up the motor and it will run forever if I want it.
My next project is the lighthouse and after that the extreme 4x4 vehicle!

Lots to Love with Loop
on July 8, 2022

I only have two complaints about this otherwise fantastic set. There are so many interesting build techniques, and I wasn’t even sure how it was all going to come together, but by the next to last bag I started to see the magic and fun in this build. The experience goes by a little too quickly, which is my first complaint. The other involves how the coaster cars transition from the elevator, to back on the track. There’s a slight gap between the elevator and the coaster rails, so my cars kept missing the track on re-entry. It took me a lot of time fiddling with the counterweight and support columns to get the elevator/track to line up at an acceptable level. I haven’t had a chance to try out the Powered Up functions yet, but I feel like that automation will make this set shine as a display piece in my city. Kudos to the design team. Truly an engineering marvel.

Good but needs constant adjustment
on July 21, 2022
Posted by: GleefulInfernox024
I enjoyed the build of this one, and the final product is both a great display piece and fun to operate. However, it's important to check the build each time you use it, as various connections will come loose, specifically on the tower itself. The first is at the very top, where the lift mechanism connects to the counterweight tower, and the second is the top-most horizontal bar connecting the lift to the tower proper. The good news is that - so far - these are the only two spots that seem to come loose, so it's an easy fix; moreover, once these connections are secured, the coaster works flawlessly. Not a super big deal, and given the stress put on these connections during operation, not surprising. That said, the coaster could be greatly improved with some stronger connections at these (and other?) stress points.

Machines Need Maintenance … or Optimization ;-)
on August 1, 2022
Posted by: StartledSandwich046
This set was a lot of fun to build - interesting support structures, slick design, very well thought out.
That being said, you have to be spot on with the instructions, then build on your own to modify behavior you don’t like. Cracking of gears, slipping of chain, misaligned lift, these are all fixed if you reduce chain length, check your axle connections, verify parts are put together right, etc.
Some tweaks are always necessary - it’s a precision machine after all. I personally was annoyed with the top part, and had issues with the counterweight coming off the track, the counterweight track coming loose, and the top separating. My fix for this is attached - top block is rebuilt completely - Teknic parts to both stabilize the counterweight wheel and apply pressure to keep it from separating - SNOT pieces added to hold the the top of the track. You may not be in the same position.
The tweaking IS the fun part, but I think the key thing to remember is that if all is tight and it won’t run stock for a minute or so, there is probably a build mistake and you should recheck things. If you want more than a minute or so of runtime before you need maintenance, it’s time to customize.
I didn’t expect nor WANT perfection out of the box. This is Lego’s coaster when it’s stock, but now that I’ve tweaked it for me, it’s MY coaster.
I would recommend this to a friend!

Excellent engineering, satisfying build
on July 8, 2022

If you thought the Haunted House was great ride engineering, wait until you see this. The vertical lift system is brilliant and remarkably reliable. The station is beautifully designed. Everything looks like it could be real. My only minor quibble is the use of stickers for a set this expensive. You also may have to invert the pins for the rubber band on the advance wheel, otherwise there isn't enough tension to keep it engaged.
