Recommendation: meh 4.46 / 5 from 127 reviews

The value for the end result was well worth it. The build became monotonous at times but still enjoyable. Highly recommend. I hope LEGO comes out with more builds like this at similar prices. Cheers.

Recommendation: meh 87 / 100 by Tom

In the end, the International Space Station is a solid set. Even buying it is at full price, you are getting a good value for both individual bricks, as well as build time. The set sits on a nice display stand and has multiple points of articulation that allow you to position it just right for your shelf. My main point of contention with the kit is the lack of Minifigures. Minifigures drive a lot of my purchasing choices when it comes to LEGO® sets. Including actual astronauts who have worked on the ISS as Minifigures to display on the base would have made this set much more appealing to me. As it is, the science geek in me still likes it. Additionally, I plan to keep it built and on display.

Recommendation: yes by Chris

It will come as no surprise at this point that I highly recommend this set. It's a fantastically designed LEGO model of one of mankind's most impressive achievements of the modern age, representing a true high-water mark of international cooperation. The model is sturdy despite representing something that was built in microgravity and has loads of great details, including at least five different spacecraft from Soyuz to the Space Shuttle (six if you assume at least one Progress capsule).

Recommendation: meh by Allen "Tormentalous" Tran

It is a great display piece and it does look good next to some of the other LEGO Ideas space sets if you have them. The price for what you get is very reasonable and all the printed pieces are a giant plus.

Recommendation: meh by Elspeth De Montes

I think a lot of adult fans will love this set, it was designed by a dedicated fan designer and has been turned into a great LEGO representation of the ISS. I can also imagine this being used as an educational tool as even the most reluctant student will become more engaged with a class when LEGO is involved.

All in all, I must say this set is one big missed opportunity. Don't get me wrong. I really like it and it makes a nice addition to my other NASA models, but I have no idea of what it is I have built – at least not from anything LEGO has provided and I'm generally left somewhat bewildered.

Recommendation: meh by Adam White

If you were a fan of the Saturn V, this is the perfect set to accompany it. It certainly doesn't have the same imposing scale, but it has an impressive visual appeal.

Recommendation: yes by Rob

It may not be one for play (every time you pick it up you'll move one of the poseable solar panels dotted all around it), nor one for those suffering from NASA fatigue in what has been a Space-heavy period for the LEGO Group, but as a detailed and accurate LEGO tribute to one of man's most important scientific ventures of the last two decades, there's nothing better. Be sure to not overlook this one, IDEAS sets tend not to hang around too long…

Recommendation: meh by CapnRex101

LEGO has produced several excellent renditions of historic spacecraft recently and 21321 International Space Station is definitely an impressive addition to the collection. The model includes extensive detail and looks magnificent in relation to the original vessel, especially across the Integrated Truss Structure where the intricate ExPRESS logistics platforms and solar arrays are accurately located.

Recommendation: meh by TobyMac

I love the model. But the build itself: just meh. The stages are very small, making it feel like your building a couple of simple sets in a row. The only challenge in the build is the sturdiness. It's tricky to apply the force needed to attach sections, but with a bit finesse you'll manage. In conclusion: Bit boring to build, but great to look at.
