Pairs perfect with the VTOL!!!

Brendan September 3, 2025

Right to the point here: Functional/Playable Vehicle. Why? Technic series aims for gears or sturdy pieces to seamlessly interact as well as be durable to a fault. This will not lose any pieces with rough play and will boast amazing space colors while doing so! Try to take time while building to avoid mistakes, as its always a pain to disassemble these sturdy technic based builds. It can turn with a lever, easily twisting a separate lever will change the entire shape of this rover!! The driver seat fits a mini figure, and these LARGE grey wheels are seemingly space oriented and I believe they're exclusive to this genre. The side build is important: it allows you to connect the airlock pods that are available in Lego System City Space sets. This is so important in fact, as its a special piece to collaborate with the Lego Technic VTOL Heavy Loader (42181), where the spaceship/plane picks up this special side build. This set pairs very well with the other City Space sets, even though its technic. Thats why I purchased it, and Im happy with this one.

Social Build

Legofan87 April 23, 2025

Hello Lego enthusiasts, this set was purchased for our inaugural Lego social meets. Perfect little set to put together while in company. The set had the perfect amount of complexity and everyone at the event each built there own Lego kit. Overall really satisfied with the purchase. Regards. M

Such a great build

RKBTCOLLECTIBLES April 13, 2025

This is one my favourite sets currently available. So much packed into a small build. While I do enjoy the largest of Lego sets, sometimes the small sets is where the magic is; designers finding ingenious ways to fit in cool mechanisms always leave sme with a smile when building. Plus this is a good play set for the kids now it is built. An easy 5/5

Spacey Sci-fi Technic!

Ms.MintySocks March 30, 2025

I love seeing Technic models outside the existing world of vehicles. I enjoyed building this and the play functions really bring it to life. Twisting a rear rod makes it "perk up", almost like a pet. It is steerable from the back, so you can watch it drive over obstacles. Love the tiny Petri dish with "life" sample.

Excellent set

DoctorDivineApricot January 14, 2025

I really enjoy this set. It is a well put together set all around. The size, the playability, the amount of time and work to put it together, all just right. As someone who has been building LEGO since the 70s, this is one of my all time favorite smaller builds.

Fun set to put together ♥️

paular295 April 22, 2024

[This review was collected as part of a promotion.] Perfect set for somebody who just get started with Lego technic or is looking for a quick build. As a non experienced builder it took me a couple of hours to put this together. Very nice and fun activity to share with someone. Very nice design and well put together. I enjoyed it a lot.

Good, decent with a lot of fun.

channons3 May 9, 2024

[This review was collected as part of a promotion.] It was an easy build, and really playful to do. My son had a lot of fun building it and is now playing with it. The quality versus price is very good..

Awesome set

MandoBiglin March 5, 2024

The surface space loader is awesome, I love the continued use of the new orange and the color scheme all around. The crane mechanism is cool as a transporter so it is not too articulate, but the mechanism is very satisfying and cool with some imagination. The overall Main transition is the sickest part, even cooler when paired with a technic hub, it's awesome. My only critique is that it should have some of the new battery pieces to power the loader.

Cool But Doesn't Really Work

ProfessorGladTortoise102 May 17, 2025

This is cool looking model but I've never been more disappointed in the fit/finish of a Lego product. The front wheels touch the adjacent pieces so much they don't spin, so you can't roll it around. The mud flap parts that attach to the wheel hub also hardly fit and pop off the wheels at the slightest touch. It's so bad I was convinced we must have made a mistake but I've taken it apart twice and can't find any errors.

I was not able to get it. They did not have it. The lady in customer service was extremely helpful. She checked stock for me, and when I wanted to cancel the order she helped me do that too!
