My son and I had so much fun putting this Lego set together. It was easy to follow directions but it took time to get everything lot together correctly which was fun. It is now a fun toy that he can play with and it seems like it will last a long time. We love lego sets.
This Lego Surface Space Loader was so fun to put together! I didn't get a chance to take a picture because my grandson loved it so much that he took it back to his house. Easy to follow the directions, great price, and as all Lego sets it was fun to put together. Love Legos!
Very cool set. It’s amazing that it is actually functional. You can steer the the car with the steering wheel, it actually turns the wheels. There is a part that you twist to raise or lower the car. It does take a while to assemble, but the directions are easily followed for older kids or with assistance. The age range is pretty accurate as this seems to be more of a car that you would want to display or carefully play with. I would not recommend to play roughly with this car. It’s a space car so there is a lot of attention to detail within the car as it comes with “specimens” to test and detectors. I would recommend this set to others. I received this in exchange for my honest review.
This Lego set is great for kids. It has various pieces to allow the user to get creative and engage in building a set. It comes with instructions and the presentation is very nice. The pieces are safe and age appropriate as advertised and when the space truck is complete its very portable. It is nice to play with and also to showcase so it's child friendly and collector friendly!
My boys absolutely love Legos! It's a fun activity for the young and old alike. This little space loader turned out to be bigger than we anticipated which is a plus. My 8 year old and 17 year old sat down together and built it which was great bc that doesn't happen a lot lol great quality for the price! It's for ages 8 and up due to the small pieces being choking hazards.
Thank you Influenster for giving me the opportunity to share my thoughts on the Lego Technic Surface Space Loader LT78. This is so cool heavy duty 435 pieces not a bad price either 45 dollars. Small piece so please be careful with children under 8 years old. Both girl and boys can play with this for hours. Definitely recommend it
This is a kinda of a cheap set and you get a ton of fun!!!
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..
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.
If you’re kids dont know what to do in their free time i would definitely recommend you to give them this this is so gun and its value for money trust me . Also its safe for kids above 8 years !! They will spend all their time on this !!
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.
