    Reviewed in the United States on October 25, 2020
    Verified Purchase
    Didn't even know this set existed until a month ago. I've always thought the ISS was really cool so when I stumbled across this set I immediately bought it. about 3 years ago I bought the Megabloks Starship Enterprise set which is an absolute Monster and took me a week to build, and this was the first set I had built since then.

    I spent about 1 and 1/2 hours on it an evening over a couple of days, the build is actually a lot easier than it looks, as you build dozens of little sub assemblies, 1 at a time, each one not being more than 5 or 6 steps. The set is broken up into numbered bags (6 of them), and the instructions clearly let you know when you've finished a bag and it's time to open up the next one, which further simplifies the building process and also cuts down on pieces laying around/hunting for parts.

    It's a fairly large set when done and fairly "spindley" (as is the real ISS), this is more a display piece than a toy for children, as many of the smaller modules and antenna/dishes are quite delicate and will come off easily. It does have movable solar arrays and a semi articulate Canada Arm, along with a docking collar that can dock a couple of the Micro scale spacecraft that are included (Space-X Dragon Capsule, Boeing Starliner, Nasa Space Shuttle. Technically there is a forth, The Russian Soyuz Capsule that is on the rear, docked as an emergency escape capsule). Every bit of decoration is printed on the pieces themselves so no stickers are required. Overall a great set and a quality looking piece.

    My only gripe, and it is minor, is the micro scale spacecraft included are too small in relation to the station itself. The included shuttle should be twice the size in order to scale properly with the station. Regardless, it still looks great and I'm glad to have it. My wallets not thrilled though because I just ordered the Saturn V set, the Lunar Lander set, and the Women of NASA set. Hopefully they will do another large scale shuttle soon because the price on the last one is now "out of this world" (dad joke).

    I really enjoyed this set, an I feel it's a great value. A lot of these bigger sets are quite a bit more. Building it was a lot of fun. This build is definitely more a show piece, not really much to play with an it's not scaled for regular sized Lego figures either (even comes with a few little mini figures). Also note there is no inside to the space station. The final product wasn't quite as sturdy as i had hoped either. It does look great though. I really liked that it didn't require any stickers, I always hate having to do the little stickers, so if the stickers are your thing sad times but for everyone else yay! I'd definitely recommend this especially for space fans, just be warned it's quite large when it's done.

    BLUF: If you had the Saturn V rocket and loved it, 100% buy this next. If you don't, consider going for the Saturn V rocket first and then come back unless you want an easier build.

    Overall a fun build and a superb final product to accompany the Saturn V rocket. A short to medium build time (half a day or less) with detail being the goal instead of the number of pieces. As a space enthusiast, the International Space Station has always drawn my interest and this model proved to synergize with that interest. The final product is a perfect shelf filler/décor for a room and the solar panels being fully adjustable help it fit in where ever that may be.

    That being said, if you like challenging and satisfying builds along with space, I think you'll get more bang for your buck with the Saturn V rocket. That would be my only recommendation, otherwise I'm completely satisfied with the purchase and am looking at the full scale lunar module/hoping Lego continues bringing out space models!

    Disfruté cada minuto que pasé armando este set, me encanta el tema del espacio y al ver que estaba en oferta no dudé en comprarlo. excelente calidad y detalle que tiene, instrucciones claras y fáciles de seguir, tomará unas horas el armarlo por completo pero ten por seguro que estarás muy entretenido como para notarlo. Podría sentirse no muy rígido y algo frágil pero es normal debido a la forma que tiene, así que solo cuidado con su manipulación, será una buena pieza de colección para tenerlo ahí en el estante, obviamente fuera del alcance de algún niño.
    (En mi caso me sobraron un puñado de piezas aún cuando seguí a la perfección la guía así que serán solo de repuesto o extras, así que si te pasó lo mismo no te preocupes, así fue hecho.)
