This is just horrible, the product is broken
on February 24, 2022
Posted by: BogdanTkachyk
App constantly says that it needs a firmware update, what's the point to buy such crap, if you can't control it at all
No, I would not recommend this to a friend.
Response from LEGOBy Jane, LEGO® Customer Service, February 25, 2022
That's definitely not the experience we want for our fans, and we're sorry about that. We've discovered the mechanism to turn on the hub can get caught on the edge of the frame. When you pushing down to turn on the hub, pull it back up and this should solve the problem. If this doesn't help, could you possibly take a quick video and give us a call or chat at bit.ly/3rVn8Te so we can take a closer look?

Biggest mistake of my life
on June 8, 2022
Posted by: PuzzledMelon057
Thought it would be good with my volvo dump truck but it ended up being nothing but problems
I am 15 hours in and still on stage 2 had to start over completely after stage 3 due to a gearbox problem
Rebuilt it and now the motors on the gearbox have no power when plugged in and connected
They worked 20 minutes ago I don't know what happened

Gear fell out
on January 20, 2022
Posted by: MadamSingingLeek
One of the small tan gears fell out as I was finishing the build. It came from deep within the body, it’s impossible to put back. Now the arms don’t raise the shovel.
No, I would not recommend this to a friend.
Response from LEGOBy Jane, LEGO® Customer Service, January 21, 2022
Oh no! It sounds like the gear wasn't quite where it needed to be. If you need assistance in determining the best way to go about rebuilding to fit it in, we're here to help! Give us a shout at LEGO.build/Service-BV and we'll be happy to take a look.

Take out thhe motors and drop the price
on January 15, 2022
Posted by: Bailey77
A real technical build yo should not attempt for your first one - my issue is with the APP which does nothing for me but calibrate the build by testing motors to the point of being ridiculous and case misalignment issues with the gearing - calibrated it for hours and have yet to get it running - too expensive for a display piece which is what I have!
No, I would not recommend this to a friend.
Response from LEGOBy Samuel, LEGO® Customer Service, January 16, 2022

Massive

Huge set, so make sure you have the space to display it. It's also heavy. Other than that, excellent product; it works. It provides hours of entertainment building this set and playing with it.
I would recommend this to a friend!

Well done Lego, well done. I was hesitant to purchase it because of the price but after spending 8 days building, correcting my errors, and testing I am extremely pleased with the purchase. Thank you.
I would recommend this to a friend!
